Question

6.L.14.4 Which is true of only animal cells?

A. Their cytoplasm contains organelles.
B. They do not have a rigid outermost layer.
C. The process of obtaining energy requires sugar.
D. They have organelles that are surrounded by membranes. ​

Answer 1

Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.

Hope this helps! Please correct me if I'm wrong :)

Answer 2

B. They do not have a rigid outermost layer.

Step-by-step explanation:

Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.

Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.
