|
Mitosis
|
The growing and dividing that cells are made from.
|
|
|
Put these words into order:
Organelles, Cells, Organs, Organism, Organ System, Tissues |
1-Organelles
2-Cells 3-Tissues 4-Organs 5-Organ System 6-Organism |
|
|
Nucleus
|
Controls the cell, contains hereditary material. (chromosomes, genes, DNA)
|
|
|
Cytoplasm
|
Fluid/Liquid in the cell - mostly salts & water.
|
|
|
Mitochondria
|
Carries out cell respiration. Gives cell energy. (Powerhouse)
|
|
|
Ribosomes
|
Builds proteins from amino acids.
|
|
|
Vacuoles
|
Stores food, water, and waste. Food molecules may ingest large molecules. Waste vacuoles may excrete waste out of the cell membrane.
|
|
|
Chloroplast
|
Carries out photosynthesis. Only in plant cells.
|
|
|
Cell Wall
|
Gives plant cell shape, structure, and protection. Only in plant cells.
|
|
|
Cell Membrane
|
Separates cell interior from environment. Controls what enters and leaves the cell. Material leaves and enters cells through pores; passive and active transport.
|
|
|
Passive Transport
|
Diffusion is included in it.
High to Low concentration. Requires NO energy. |
|
|
Active Transport
|
Low to High concentration.
REQUIRES ENERGY |
|
|
Plant Cells Shape is...
|
Rectangular
|
|
|
Animal Cells Shape is...
|
Circular
|
|
|
What do the mitochondria and ribosomes contribute to each other?
|
The mitochondria releases energy to allow the ribosomes to produce proteins that the mitochondria needs to function.
|
|
|
ATP
|
Form of energy.
|
|
|
Robert Hooke
|
first person to use the word "cells"
|
|
|
Matthias Schlieden
|
determined that all plant cells were made of cells.
|
|
|
Theodore Shwann
|
determined that all animal cells were made of cells,
|
|
|
Rudoph Virchow
|
determined that all cells come from existing cells.
|
|
|
The Cell Theory
|
1-All living things are made up of cells.
2-Cells are the basic unit of structure and function in living things. 3-New cells are produced from existing cells. |
|
|
The 2 cellular boundaries
|
Cell Wall-only in plants, has pores, supports, shapes, protects the cell, outside of the cell membrane.
Cell Membrane-found in all cells, semi permeable, regulates what enters and leaves the cell, made up of a lipid bilayer. |
|
|
Prokaryotic Cells
|
-Doesn't enclose DNA in a nucleus.
-No nucleus. -Reproduce asexually. -Example: Bacteria |
|
|
Eukaryotic Cells
|
-DNA is enclosed in the nucleus.
-Have a nucleus. -Reproduce asexually. -Example: Plant and Animal cells |
