Cells and Bacteria Homework

Cells and cell structures:

Cells are the building blocks of life. All living things are made of cells. Cells live in groups called tissues, and they also have functions like organelles, cytoplasm, lysosomes, peroxysomes, and membranes, membranes lets good stuff in and keeps bad stuff out, like we have organs. Cells have different features and they can look very different, but they all have a DNA which orders them around to do certain things. Plant cells have rigid cell walls that maintains their shape.

Things animal cells don’t have:

• Cell wall
• Chloroplast
• Vacuole

Things both cells have:

• Nucleus
• Plasma membrane

Bacteria:

Bacteria are single-celled microscopic organisms. Makes up Animals, Plants, Fungi, Protists and Archaea. Bacteria is all around us, there are good and bad bacterias. Bacteria also come in lots of different shapes and sizes. Some can’t move and some use tiny hairs and little strands to move. Bacteria’s nuclear material is not surrounded by a membrane. Bacteria doesn’t have many complex organelles like plant and animal cells do, all they have is a nucleoid and ribosomes

What a basic bacteria has:

• DNA
• Nucleus
• Plasma membrane
• Cell wall
• Ribosomes

What basic bacteria’s don’t have compared to plant and animal cells:

• Vacuole
• Chloroplast

And many others, but this is the simplest things on it.
