Question

1. compare: what structures are present in an animal cell, but not in a plant cell? what structures are present in a plant cell, but not in an animal cell? 2. fill in: name the organelle or organelles that perform each of the following functions. a. __________ convert sunlight to chemical energy. b. the ________, the ________, and the ________ support the plant cell and help it to maintain its shape. c. ________ store food or pigments. d. __________ convert food into energy. they are found in plant and animal cells. activity c: bacterial cells get the gizmo ready: • select the bacterial cell tab and click sample. 1. label: locate each organelle in the bacterial cell. label the organelles in the diagram below. 2. compare: what structures are present in a bacterial cell, but not in a plant or animal cell? what structures are present in plant and animal cells, but not in a bacterial cell?

Explanation:

1. Animal cells have centrioles which plant cells lack. Plant cells have a cell wall, chloroplasts, and large central vacuoles that animal cells do not.

2A. Chloroplasts convert sunlight to chemical energy through photosynthesis.
2B. The cell wall, cell membrane, and cytoskeleton support the plant cell and maintain its shape.
2C. Plastids (such as chromoplasts for pigments and leucoplasts for food storage) store food or pigments.
2D. Mitochondria convert food into energy via cellular respiration in both plant and animal cells.
For the bacterial cell: Bacterial cells may have flagella, pili, and a capsule which are not in plant or animal cells. Plant and animal cells have membrane - bound organelles like a nucleus, endoplasmic reticulum, Golgi apparatus etc. that bacterial cells lack as bacteria are prokaryotes.

Answer:

1. Structures in animal cell but not plant cell: Centrioles. Structures in plant cell but not animal cell: Cell wall, chloroplasts, large central vacuole.

2A. Chloroplasts
2B. Cell wall, cell membrane, cytoskeleton
2C. Plastids
2D. Mitochondria
Activity C - 1: (Since no diagram labels provided in answer as it requires visual work, but organelles in a bacterial cell usually include cell wall, cell membrane, cytoplasm, nucleoid, ribosomes, sometimes flagella, pili etc.)
Activity C - 2: Structures in bacterial cell but not plant/animal cell: Flagella (in some bacteria), pili, capsule. Structures in plant and animal cells but not bacterial cell: Nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria (in a more complex form), lysosomes etc.
