chloroplast |
Only in plant cells, makes food for plant cells,
|
|
What are the main differences between a plant cell and an animal cell?
|
On a plant cell the vacuole would be huge since it holds a lot of water; Plants have cell walls that supports the cell |
|
cell
|
The smallest part of your body that carries out the activities of life |
|
tissue
|
a group of the same kind of cells working together doing the same job |
|
organ
|
A group of tissues that work together to carry out a life process
|
|
Cell wall
|
A Cell wall is a rigid supporting the layer that surrounds the cells of the plants and some other organisms. Only Plant Cell
|
|
Cell membrane
|
A Cell membrane is a thin flexible barrier that surrounds a cell and controls which substances pass in and out of the cell. Both Animal and plant cells |
|
Organelle
|
a tiny cell structure that carries out a specific function within the cell |
|
Cytoplasm
|
a gel-like fluid that fills the region between the cell membrane and the nucleus |
|
Chloroplast
|
an organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food. Only plant cells. |
|
Mitochondria
|
a rod-shaped organelle that converts energy in to food molecules that the cell can use to carry out its functions |
|
Vacuole |
a sac-like organelle that stores water, food and other materials. |
|
What does the cell theory state?
|
1.all organisms are composed of one or more cells 2.the cell is the basic unit of structure and organization in organisms 3.all cells come from other cells |
|
ribosome
|
a small grain-shaped organelle in the cytoplasm of a cell that produces protein |
|
Endoplasmic Reticulum
|
an organelle that forms a maze of passage ways in which proteins and other materials are carried from one part of a cell to the other |
|
Golgi body
|
an organelle in a call that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them and distributes them to other parts of the cell |
|
lysosome |
small round structures containing chemicals that break down certain materials in the cell into smaller ones (only animal cells) |
|
element |
any substance that cannot be broken down into simpler substances |
|
compound |
when two or more elements are combined |
|
carbohydrates |
an energy-rich compound made of the elements carbon, hydrogen, and oxygen (sugars and starches) |
|
lipids |
an energy-rich compound made of the elements carbon, hydrogen, and oxygen (fats, oils and waxes) |
|
proteins |
large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur (meat, eggs, fish, nuts, beans) |
|
enzyme |
a type of protein that speeds up a chemical reaction in living things |
|
nucleic acids |
DNA - genetics RNA - production of protein |
|
selectively permeable |
some substances can pass through the membrane while others can not (selects which can pass) |
|
diffusion |
the main method by which small molecules move across the cell membrane |
|
osmosis |
the diffusion of water molecules through a selectively permeable membrane |
|
passive transport |
the movement of materials through a cell membrane without using cellular energy |
|
active transport |
the movement of materials through a cell membrane using cellular energy |
