SCIENCE QUESTION

Chloroplasts are organelles found only in plant cells. Why are chloroplasts not needed in animal cells?

Animals have bones for support and don't need rigid chloroplasts to provide structure.

Animal cells store DNA in the nucleus, not in chloroplasts like plants

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Animals obtain energy from eating other things, not from photosynthesis.​

Answer 1

Step-by-step explanation:

1:

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

2.

The basic plant cell has a similar construction to the animal cell, but does not ... It does have additional structures, a rigid cell wall, central vacuole, ... namely xylem, which is involved in structural support and water conduction, ... to provide energy, particularly when light isn't available for the chloroplasts to produce energy.

3.

What structures does a plant cell have that an animal cell does not have? ... The centrosome is a region near the nucleus of animal cells that functions as a ... Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. ... Like mitochondria, chloroplasts also have their own DNA and ribosomes.

4. Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant ... Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for ... Like mitochondria, chloroplasts also have their own DNA and ribosomes. ... The central vacuole also functions to store proteins in developing seed cells.

5. Animals cannot use radiant (light) energy in this way. They must ... What change had the plant made to ... However, Earth's atmosphere has not always contained oxygen gas. During ... form of glucose or they eat other animals that ate plants.

Answer 2

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Step-by-step explanation:

Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.
