What are Eukaryotic cells?
Complex cells including all animal and plant cells
1 of 21
What are Prokaryotic cells?
Smaller and simpler cells e.g. bacteria
2 of 21
What is a Eukaryotes?
Organisms made up of eukaryotic cells
3 of 21
What is a Prokaryote?
Sigle-celled organism
4 of 21
Nucleus
Controls the activities of the cell
5 of 21
Cytoplasm
Where the chemical reactions needed for life take place
6 of 21
Cell membrane
Controls what substances go in and out of the cell
7 of 21

Site of respiration
8 of 21

How are sperm cells specialized?
Long tail and streamlined head to help it swim to the egg. Lots of mitochondria to provide energy. Head contains enzymes to digest egg membrane
13 of 21
How are nerve cells specialized?
Long bodies to to cover more distance. Branched connections to connect to other nerve cells and make networks around the body.
14 of 21
How are muscle cells specialized?
Contain lots of mitochondria so that they have enough energy to contract.
15 of 21
How are root hair cells specialized?
Long fibers so that they have a bigger surface area and can absorb more water and mineral ions.
16 of 21
How are the xylem and phloem specialized?
They are hollow and have very few sub cellular organisms so that substances can flow through them.
17 of 21
What happens during mitosis?
1. DNA replicates in cell. 2. Chromosomes line up at the center of the cell. The spindles pull them to opposite sides. 3. The cytoplasm splits. 4. 2 identical cells are formed
18 of 21
What are stem cells?
Undifferentiated and specialized cells that have the potential to become any type of cell.
19 of 21
How are embryonic and adult stem cells different?
Embryonic stem cells have the potential to become any type of cell. They are found in embryo's. Adult stem cells are only found in certain places e.g. bone marrow, and can't turn into any cell, only turn into certain cells e.g. blood

What are the issues around embryonic stem cell research?
Each embryo could have been a life. It's murder. The embryo had rights. The embryo can't decide what it wants, so there is no permission to take it's stem cells.
