Plant and animal cells are different because
A: plant cells do not have a nucleus or mitochondria
B: animal cells do not have DNA or ribosomes
C: plant cells do not have a cell membrane
D: animal cells do not have a cell wall or chloroplasts
I think the answer is C.
oh my gosh just tellllll meeee
The correct answer is D: animal cells do not have a cell wall or chloroplasts.
Plant cells have a cell wall made of cellulose, which is a rigid structure that provides support and protection. Animal cells do not have a cell wall.
Additionally, plant cells contain chloroplasts, which are responsible for photosynthesis and contain the pigment chlorophyll. Animal cells do not have chloroplasts.
Both plant and animal cells have a nucleus, mitochondria, DNA, ribosomes, and a cell membrane. The main difference between plant and animal cells lies in the presence or absence of a cell wall and chloroplasts.
Actually, the correct answer is D: animal cells do not have a cell wall or chloroplasts.
To arrive at this answer, let's go through the options together:
A: Plant cells do have a nucleus and mitochondria. In fact, both plant and animal cells contain a nucleus, which houses the genetic material (DNA) of the cell, and mitochondria, which are the powerhouse of the cell, responsible for energy production.
B: Animal cells do have DNA and ribosomes. Again, both plant and animal cells contain DNA as their genetic material, and ribosomes are present in both cell types for protein synthesis.
C: Both plant and animal cells have a cell membrane. The cell membrane is a universal feature of all cells, serving as a protective barrier and controlling the movement of substances into and out of the cell.
D: Animal cells do not have a cell wall or chloroplasts. The cell wall is a unique characteristic of plant cells, providing structural support and protection. On the other hand, chloroplasts, which are responsible for photosynthesis (the conversion of sunlight into energy), are also specific to plant cells.
So, in summary, the correct answer is D, as animal cells lack a cell wall and chloroplasts, whereas plant cells possess these structures.
