QuestionAnswer
difference between the eukaryotic and the prokaryotic cell eukaryotic, has membrane bound nucleus, prokaryotic does not
levels of cell organization cell, tissue, organ, organ system, organism
4 results of cell division growth, repair, replacement, and reproduction
occurs in plants only and is similar to a cell walll down the middle of the plant cell cell plate
a part of the shoot system stem of a flower
unspecialized cells that may develop into different types of cells (only in animals) stem cells
chromosomes line up across the middle of the cell metaphase
groups of different tissues working together organs
do not have cell plates animal cells
disappears during prohase of mitosis nuceolus
occcurs during interphase DNA copying
two new identical nuclei form telephase
two sister chromatids joined by a centromere duplicated chromosome
2 major organ systems of plants root system and shoot system
its purpose is to form the protective outer layer of skin epithelial tissue
time it takes a cell to complete the cell cycle depends on the type of cell that is dividing
similar types of cells grouped together to perform specific tasks tissues
4 major types of tissues found in animals muscle, connective, nervous, epithelial
carries messages to and from the brain nervous tissue
causes movement muscle tissue
3 types of plant tissue vascular, dermal, ground
shortest phase of mitosis- chromosomes line up at center of cell metaphase
takes place in the ground tissue of plants photosynthesis
1. cells grow and develop during interphase 2. cells reproduce during the mitotic phase 2 phases of the cell cycle
process in which cells coming from the same cell become different types of cells cell differentiation
take about 24 hours to complete cell cycle human cells
pairs of identical chromosomes are held together by a centromere (growth and chromosome replication) During s stage of interphase
period of growth and development/ cell spends most of life in this phase interphase
unspecialized cells in plants meristems
is considered to be an organ plant leaf
2 stages of mitotic phase mitosis and cytokinesis
cells copy their DNA during s stage of interphase
the nucleus divides first, then the cytoplasm divides mitotic phase
the dupllicating of cells is not the same for all cells depends on the type of cell that is duplicating
the division of a cell nucleus mitosis
divides by the cell membrane pinching together until the two cells split apart animal cell

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
