3
cytokinesis is...
the division of the chloroplasts
the division of the mitochondria
the division of the cytoplasm
the division of the nucleus
4
mitosis is the division of the nucleus
False
True
5
cellular biology: which 2 answers are the 8 characteristics of life?
reproduction, response to stimuli, metabolism, heredity

6
cell energetics: an autotroph produces its own food for energy (usually through photosynthesis)
True
False
7
cellular biology:
study thiss
recreate this on paper
8
Plant vs animal cells: both have a cell wall
False
True
9
cellular biology: what makes animal and plant cells differ?
animal cells do not have chloroplasts.
animal cells do not have centrioles.
plant cells don't have a cell membrane.
10
cell division: why does the cell divide instead of continuing to grow? (2)
if the cell gets too large, it becomes too overwhelmed with Info in the DNA
cells divide to regulate organism growth
the cells divide kill cancer cells
cells divide to ease the moving of nutrience and waste in and out the cell
11
cell energetics: what are the two cycles in cellular respiration and their locations?
glycolosis- cytosol and kreb cycle- mitochondria
kreb cycle- cytosol, glycolosis- mitochondria
calvin cycle- mitochondria and kreb cycle- cytosol
12

this phase of the interphase, the cells will assemble the special structures needed for cell division.
G2 phase
S phase
G1 phase
16
cellular biology: what did Robert Hooke contribute to the cell theory?
discovered that "cells" could multiply.
he discovered the mitochondria.
discovered the cell membrane.
he was the first to decribe what he saw as "cells" under a microscope.
17
Plant vs animal cells: both have a(n) endoplasmic reticulum (rough and smooth er)

idk
G1 phase
25
cell division: what are the 4 phases of the cell cycle- in order?
G1, S, G2, mitosis, cytokinesis
prophase,interphase,anaphase,telophase
