1. I carry out special jobs in a cell:
2. I’m an important concept and I have three main points; the last is that all cells come from existing cells:
3. I make up the two layers of the cell membrane:
4. I describe the cell membrane structure because it is flexible and could be compared to an arrangement of tiles:
5. I am the type of cell that has a nucleus; animal and plant cells are me:
6. I am the type of cell without a nucleus; bacteria are me:
7. I help molecules diffuse across a membrane through transport proteins:
8. I have two types, smooth and rough; I help produce proteins and lipids:
9. I contain enzymes and defend cells from viruses and bacteria; animal cells have lots of me:
10. I am an organelle shaped like a bean; I provide energy for a cell:
11. I am a cylinder-shaped organelle in animal cells, and I help make flagella:
12. I am the outer edge that separates a cell from the outside environment; I control what goes in and out of a cell:
13. I receive signals from molecules and make sure the right cell gets the right signal at the right time:
14. I’m a sac filled with fluid inside a cell; I store materials the cell needs:
15. I’m a little organelle that carries materials from one part of the cell to another; I don’t live long, but I can be recycled:

Answer 1

Organelles are the different parts of a cell that carry out special jobs. The concept that all cells come from existing cells is part of the cell theory. The two layers of the cell membrane are made up of phospholipids.

Step-by-step explanation:

The different parts of the cell are called organelles.

The concept that all cells come from existing cells is part of the cell theory.

The two layers of the cell membrane are made up of phospholipids.

The cell membrane structure is described by the fluid mosaic model.

The type of cell that has a nucleus is the eukaryotic cell.

The type of cell without a nucleus is the prokaryotic cell.

Molecules can diffuse across a membrane through facilitated diffusion.

There are two types of endoplasmic reticulum: smooth and rough, which help produce proteins and lipids.

Enzymes that defend cells from viruses and bacteria are found in lysosomes.

The organelle that provides energy for a cell is the mitochondria.

The organelle that helps make flagella in animal cells is the centriole.

The outer edge that separates a cell from the outside environment is the cell membrane.

Receptors receive signals from molecules and ensure that the right cell gets the right signal at the right time.

A vacuole is a sac filled with fluid inside a cell that stores materials the cell needs.

Vesicles are small organelles that carry materials from one part of the cell to another and can be recycled.

Answer 2

receive signals from molecules and make sure the right cell gets the right signal at the right time:
