Plant and Animal Cells

S5L3:Students will diagram and label parts of various cells (plant, animal, single-celled, multi-celled) Use magnifiers such as microscopes or hand lenses to observe cells and their structure. 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. 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 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 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 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 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 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.
