Transcript Plant and Animal Cells

Plant and Animal Cells
S5L3:Students will diagram and label parts of various
cells (plant, animal, single-celled, multi-celled)
a. Use magnifiers such as microscopes or hand lenses to
observe cells and their structure.
b. Identify parts of a plant cell (membrane, wall, cytoplasm,
nucleus, chloroplast) and of an animal cell (membrane,
cytoplasm, and nucleus) and determine the function of the
parts.
c. Explain how cells in multi-celled organisms are similar and
different in structure and function to single-celled
organisms.
A cell is a tiny part of a living thing.
Plant Cell
A plant cell is surrounded by a cell wall. This stiff
wall protects the cell. The walls of the plants cells
stick to each other to give the plants its shape.
Plant Cell
Just inside the cell wall is the cell membrane. This
thin membrane allows water and nutrients to pass
into the cell. It allows wastes, including oxygen, to
pass out of the cell. It also stops some materials
from getting into the cell and injuring it.
Near the center of the cell is the nucleus. The
nucleus controls the cell’s growth. The plant’s
genes are in the nucleus of the cells.
The green chloroplasts in the cell produce
food for the plant. The chloroplasts combine
sunlight, water, and carbon dioxide from the
air to produce sugars. These sugars give the
plant energy to plant and bloom.
The rest of the plant cell is filled with
cytoplasm. Cytoplasm is much like jelly. Much
of the cell’s work takes place in the cytoplasm.

Animal cells DO NOT have
cell walls and they DO NOT
have chloroplasts!

d. A plant cell can become a nerve cell.
4. Which statement is true?
a. The cell wall allows materials to pass in and out of
cells.
b. Both plant and animal calls have a cell membrane.
c. The genes for plant cells are in the cytoplasm.
d. A plant cell produces food in its nucleus.
