What does plants use to make food from the sun?
Plants use a process called photosynthesis to convert solar energy into food. They use chlorophyll, a pigment found in the chloroplasts of their cells, to capture sunlight and convert it into chemical energy. This energy is then used to combine carbon dioxide and water to produce glucose, which the plant uses as its primary source of nutrition.

Plants use chloroplasts to make food from the sun by a process called photosynthesis. Chloroplasts contain chlorophyll which captures sunlight and converts it into chemical energy that is used to make glucose from carbon dioxide and water.
What organelle is responsible for allowing the passage in and out of the cell-"the gate keeper"?
*
1 point
Chloroplast
Plasma membrane
Mitochondria
Cytoplasm
Plasma membrane is responsible for allowing the passage in and out of the cell. It acts as a gatekeeper of the cell by regulating the movement of substances such as nutrients, waste products, and ions in and out of the cell. The plasma membrane is made up of a phospholipid bilayer and various types of proteins which work together to control the movement of substances.
What is the difference between prokaryote and eukaryote cells?

prokaryote cells are multicellular
eukaryote cells do not have a nucleus
They both have a nucleus
prokaryote cells do not have a nucleus and eukaryote cells do have a nucleus
The main difference between prokaryotic and eukaryotic cells is that prokaryotic cells do not have a nucleus and eukaryotic cells do have a nucleus. Prokaryotic cells are typically smaller and simpler in structure, with no membrane-bound organelles, while eukaryotic cells are larger and more complex, with a variety of membrane-bound organelles such as mitochondria, lysosomes, and endoplasmic reticulum. Prokaryotic cells are typically unicellular, while eukaryotic cells can be unicellular or multicellular.
Why do animal cells have a small vacuole and not a large central vacuole like plant cells?
Animal cells have a small vacuole and not a large central vacuole like plant cells because animal cells have different functions compared to plant cells. While plants use the central vacuole to store water, nutrients, and waste products, animal cells do not need to store large amounts of water or other substances in a vacuole. Instead, animal cells rely on other organelles such as lysosomes to store and recycle waste products, and regulate the cell's internal environment. Additionally, animal cells have a more complex and flexible shape compared to plant cells, which require a smaller vacuole to allow for movement and adaptation to their environment.
What are the 2 things that plant cells have that animal cells do not
The two things that plant cells have that animal cells do not are a cell wall and chloroplasts. The cell wall is a rigid layer outside the cell membrane, providing support and protection to the cell. It is unique to plant cells and not found in animal cells. Chloroplasts are organelles that contain chlorophyll, and are responsible for photosynthesis in plant cells. Chloroplasts are also found exclusively in plant cells and are absent in animal cells.
2. Andrea uses the $5 coupon to purchase a CD at CD Heaven Music Store. If the retail price of the CD is $18.50, what percent of the retail price does she save by using the coupon?
4 a) What percent discount is the same as a discount of 1/3?
b) If the Surround Sound Theatre normally charges $15 per ticket, how much is saved by attending the Theatre on Tuesday?
c) What percent of the normal price is saved if two tickets are purchased?
a) To find out what percent discount is the same as a discount of 1/3, we can use the formula:
percent discount = (discount ÷ original price) × 100%
Since the discount is 1/3, we can write this as:
percent discount = (1/3 ÷ 1) × 100%
percent discount = 33.33%
Therefore, a discount of 1/3 is equivalent to a 33.33% discount.
b) If the Surround Sound Theatre normally charges $15 per ticket, and the Tuesday price is $12, the amount saved by attending on Tuesday is:
$15 per ticket - $12 per ticket = $3 per ticket saved
Therefore, by attending the Theatre on Tuesday, a person saves $3 per ticket.
c) If two tickets are purchased, the normal price is:
2 tickets × $15 per ticket = $30
On Tuesday, each ticket costs $12, so the total cost of two tickets is:
2 tickets × $12 per ticket = $24
The amount saved by purchasing two tickets on Tuesday is:
$30 - $24 = $6
To find out what percent of the normal price is saved by purchasing two tickets on Tuesday, we can use the formula:
percent discount = (amount saved ÷ normal price) × 100%
In this case, we have:
percent discount = ($6 ÷ $30) × 100%
percent discount = 20%
Therefore, by purchasing two tickets on Tuesday, a person can save 20% of the normal price.
5 What would be the sale price of a $90 pair of boots at the Cool Fashions Clothing Store
Without knowing the discount or sale percentage, it is impossible to determine the sale price of a $90 pair of boots at the Cool Fashions Clothing Store. If the discount or sale percentage is given, the sale price can be calculated by subtracting the discount amount from the original price.
For example, if there is a discount of 20%, the calculation would be:
Discount amount = 20% of $90 = 0.2 × $90 = $18
Sale price = $90 - $18 = $72
Therefore, the sale price of the $90 pair of boots would be $72 with a 20% discount.
6 Andy owns a new winter coat that he likes to wear. He bought a second new coat at the Cool Fashions Clothing Store for $81.89 because it was on sale. Do you think Andy made a smart purchase? Explain why, or why not.
As an AI language model, I cannot determine whether Andy made a smart purchase without additional information.
It depends on whether the second new coat was a good value for Andy, the quality of the coat, the use he has for the coat, and if he needed a second coat. If the second coat is of a good quality, the cost is reasonable, and Andy has reasons to have a second coat, then the purchase might have been smart.
However, if the coat is not of good quality and Andy didn't need a second coat, it might not have been a smart purchase.
Therefore, it depends on many factors and it is up to individual judgment whether the purchase was smart or not.
