2) If a cell has 24 chromatids, how many duplicated chromosomes will it have?
3) What type of cell pinches in the middle when it divides?
4) Cells divide in order to do what things?
5) Know the differences between prokaryotes and eukaryotes.
6) Explain what cell differentiation is.
7) What are the 3 types of tissue found in plants?
8) Which type of plant tissue is where photosynthesis occurs?
9) What are plants two major organ systems?
