Unit 4 cells to organisms
Eukaryotic has a nucleus
has a nucleus
Mitosis and meiosis
MItosis 2 identical cells
sometimes people have an extra pair of chromosomes with is down syndrome
meiosis 4 cells
humans have more then most living thing because we are very complex
You need 23 chromosomes from each person witch make a child
cancer is uncontrolled mitosis

A process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in haploid cell
Function of Mitosis
Cellular Reproduction & general growth and repair of the body.
Type of Reproduction (Mitosis)
Meiosis is Genetically
Mitosis is Genetically
Crossing Over (Mitosis)
No, crossing over can not occur.
Number of Divisions (Meiosis)
Number of Divisions (Mitosis)
Chromosome Number (Meiosis)
Reduced by half
Chromosome Number (Mitosis)
Remains the same
Sex cells only: Female egg cells or Male sperm cells
Makes everything other than sex cells
Store waste products, nutrients, and water. In plant cells it also store nutrients, and regulates turgor pressure in the cell.
DNA is found in the nucleus, RNA is also made here; surrounded by a membrane; controls all cell activites
This produces ribosomes; found in the nucleus
Play a role in mitosis (cell division), in animal cells only - Ring of nine groups of fused microtubules. Three microtubules in each group. These are part of the cytoskeleton. Inherited from your father.
Use carbon dioxide, water and sunlight to carry out photosynthesis. Found in plant cells and some protists. They reflect green light while absorbing all other colors. *contain DNA
Double layer of phospholipids (lipid bilayer) that surrounds the cell; regulates what enters and leaves the cell.
Smooth Endoplasmic Reticulum
Assembles membrane lipids and detoxifies the cell of drugs; no ribosomes on this organelle.
Rough Endoplasmic Reticulum
Proteins are made on the endoplasmic reticulum's ribosomes. They are collected inside the endoplasmic reticulum and transported throughout the cell. Transports and modifies organelles, highway for cell.
Assembles proteins; free ribosomes make proteins that will stay in the cell. Attached ribosomes (attached to the ER) make proteins that will be transported out of the cell.
Helps maintain cell shape. Its primary importance is in cell motility. It makes the cell move internally and externally.
Made of microfilaments and microtubules. (protein strands)
plant and animal cell: strands that contain the genetic material that tells the cell how to function.
A small structure made of a lipid bilayer used to transport materials through the cell.
part of the cytoskeleton - made of tubulin-used to move substances around the cell - framework of cell
What are the products of photosynthesis?
O₂ + C₆H₁₂O₆
I discovered that plants are made of cells.
I saw cells in cork and came up with the word "cells to describe them.
I discovered that there are microscopic organisms in pond water.
I developed the cell theory and came to the conclusion that all cells come from other cells
