Cells

____________By: Trisha Nguyen

According to our science textbook, cells are the smallest functional and structural unit of all living organisms; usually consists of a nucleus, cytoplasm, and a membrane. There are two types of cells- Prokaryotes and Eurkaryotes.

According to our science textbooks, organelles are one of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function, similar to oragns in a body.

Prokaryotes-

Eukaryotes-

Animal Cells-

Plant cells-

Organelles and their functions-

Prokaryotes are a type of cell in which the cell is a single-cell and does not contain a nucleus or any membrane-bound organelles. Examples of prokaryote cells would be bacteria being the most common and archaea.

Eukaryotes are a type of cell in which the organism is made up of cells that have a nucleus enclosed by a membrane. Examples of eukaryote cells would be protists, animals, plants, and fungi but not archaea or bacteria.

The Large central vacuole is the organelle that stores water and other materials.

Cloroplast are organelles that produces sugar as food using sunlight and energy. (photosynthesis)

The Golgi complex is the organelle that transport, label, packages, sorts, and finish proteins.

Ribosomes are organelles that produces protein and is also where protein photosynthesis occurs in.

Lysosomes contain digestive enzymes in which the organelle digests food particles, wastes, cell parts, and foreign invaders.

The Endoplasmic Reticulum (ER) is the organelle that produces lipids, breaks down drugs and other substances, and delivers proteins to the Golgi complex.

The Nucleus is the organelle that contains the cell's DNA and is the control center of the cell.

The Mitochondria produces energy (ATP) for the cell by breaking down food particles.

Plant cells and animal cells are both a type of eukaryote cells. Both are similar to each other but still have some differences. For example, plant cells have a cell wall and cloroplast while animal cells don't. A cell wall is a structure that surrounds the whole cell which gives the cell support. Cloroplast is an organelle which produces sugar as food from sunlight and energy. This process is also known as photosynthesis Also, the structure of the animal cells and plant cells are a bit different. Plant cells have a more square-like shape to them while animal cells are more round.
