Chloroplasts play an important role in energy production in plant cells. However, some parts of a plant, like the roots, lack chloroplasts. In one to two sentences, explain the most likely pathway for root cells to obtain energy, and identify the organelles involved.
Root cells obtain energy through the process of cellular respiration, which occurs in the mitochondria. Glucose, produced through the breakdown of organic molecules in the roots, is converted to ATP in the mitochondria to provide energy for cellular functions.
In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.
Animal cells do not require a cell wall because they rely on a flexible plasma membrane to provide structural support and maintain cell shape. Unlike plant cells, animal cells do not need to withstand mechanical stresses from environmental factors. Instead, they have cytoskeletal elements such as microfilaments and microtubules that help maintain cell shape and provide mechanical support.
Similarly, animal cells do not require a central vacuole because they do not engage in large-scale nutrient storage or cell enlargement like plant cells do. Animal cells obtain nutrients directly from their surroundings or store them in specialized organelles like lysosomes or lipid droplets. The absence of a central vacuole in animal cells allows for greater flexibility and versatility in their functions.
In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular)
In an amoeba, the process of digesting food involves phagocytosis, where the amoeba engulfs food particles with its pseudopods and forms a food vacuole. Enzymes within the vacuole break down the food into smaller molecules, which are then absorbed by the amoeba for energy and nutrition.
In a mouse, the process of digesting food is more complex due to its multicellular nature. Food intake begins with the mouth, where mechanical digestion takes place through chewing. The food then enters the stomach, where it is mixed with digestive enzymes and acid for chemical breakdown. Further digestion and absorption of nutrients occur in the small intestine, while waste material is eliminated through the large intestine.
Overall, while both amoebas and mice digest food to obtain nutrients, the process is more intricate in mice, involving specialized organs and various stages of digestion to accommodate their multicellular structure.

can you right a paragraph answering that in 7th grade terms
Root cells obtain energy through the process of cellular respiration. This happens in the mitochondria, which are like tiny powerhouses inside the cells. Instead of using sunlight like chloroplasts, mitochondria break down sugars and other molecules to create energy in the form of ATP. So even though roots don't have chloroplasts, they can still get energy to do their important job of absorbing nutrients and water from the soil.
simplify that paragraph to 1 to 2 sentences
Root cells get energy through cellular respiration in the mitochondria, which produce energy from sugars and other molecules.
In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions as good as an 8th grader
Animal cells do not require a cell wall because they have a flexible plasma membrane that provides structure and shape to the cell. This flexibility allows animal cells to move and change shape as needed. Additionally, animal cells do not necessarily need a central vacuole because they do not store large amounts of nutrients like plant cells do. Instead, animal cells obtain nutrients directly from their environment or store them in specialized organelles. While the absence of a cell wall and central vacuole does not limit the functions of animal cells, it allows them to have greater versatility and adaptability in their activities.
simplify that a bit
Animal cells do not have a cell wall because they have a flexible membrane that provides support. They also don't have a central vacuole because they don't store as many nutrients as plant cells. This allows animal cells to be more adaptable and versatile in their functions.
In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .(4 points)
When comparing the process of digesting food between an amoeba and a mouse, there are several key differences. In an amoeba, digestion primarily occurs through phagocytosis, where the amoeba engulfs food particles and forms a food vacuole to break them down with enzymes. In contrast, a mouse has a more complex digestive system. Food is ingested through the mouth and mechanically broken down through chewing, then chemically digested in the stomach with enzymes and acid. Further digestion and absorption of nutrients occur in the small intestine, and waste material is eliminated through the large intestine. The mouse's digestive system is adapted for the breakdown of a wide variety of food types, while the amoeba's process is more simplified due to its unicellular nature.
simplify that
An amoeba digests food by engulfing it and breaking it down inside a vacuole, while a mouse has a more complex digestive system. The mouse's process involves chewing and chemically breaking down food in the stomach, followed by absorption in the small intestine and elimination of waste. The mouse's digestive system is adapted to handle a wider variety of food compared to the simpler process in amoebas.
simplify just a bit more
Amoebas eat by engulfing and breaking down food inside a vacuole, while mice have a more complex process. Mice chew and chemically break down food in the stomach, absorb nutrients in the small intestine, and eliminate waste. The mouse's digestive system can handle a wider variety of food compared to amoebas.

In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions. explain in simple words plz
Animal cells do not need a cell wall because they have a strong and flexible outer covering called the plasma membrane that supports and protects them. Unlike plant cells, animal cells can change their shape and move around, which is why they don't need a rigid cell wall. Additionally, animal cells don't have a central vacuole like in plant cells because they don't need to store as much water or nutrients. Instead, animal cells have smaller storage compartments called vesicles that can hold important molecules until they are needed.
now summarize this to make it a bit shorter and use really simple words plzz
Animal cells don't have a cell wall like plants because they can change shape and move. They also don't have a big central vacuole because they don't need to store as much stuff. Instead, they have a strong skin called the plasma membrane and little storage compartments called vesicles.
Summarize and use simple and easy kids words for this.
An amoeba digests food through phagocytosis, engulfing food particles and breaking them down in a vacuole. In contrast, a mouse has a more complex digestive system involving chewing, chemical digestion in the stomach, nutrient absorption in the small intestine, and waste elimination. The mouse's system is adapted for a wider variety of food compared to the simplified process in amoebas.
An amoeba eats by wrapping its food in a bubble called a vacuole and breaking it down. But a mouse has a more complicated way of eating. It chews its food, then the food goes into its stomach. In the stomach, special chemicals help break down the food. After that, the important parts of the food are absorbed in the small intestine. The parts the mouse doesn't need come out as waste. Mice can eat many different kinds of food, while amoebas have a simpler way of eating.
you can add some bigger words, not that simple. (remember not too hard)
An amoeba eats by wrapping its food in a bubble-like compartment called a vacuole and breaking it down. However, a mouse has a more complex digestive system. It starts by chewing its food, which then travels to the stomach. In the stomach, special chemicals called enzymes help break down the food into smaller pieces. Next, the important parts of the food are absorbed in the small intestine. Anything that the mouse doesn't need is eliminated as waste. Mice have a greater ability to eat a wide variety of foods due to their more intricate digestive process, while amoebas rely on a simpler way of obtaining nutrients.
