A multicellular organism is different from a unicellular organism because:
it contains many cells that perform specialized function that are complex while unicellular is made up of only one cell.

a eukaryotic cell, where is the genetic material (DNA) stored?
The nucleus
300
Besides storage, what does a vacuole provide in a plant cell?
Structure
300
describes the relationship between the nucleus and the rest of the cell
DNA within the nucleus contains instructions for all cell activities

A. Prokaryotic Bacterial Cell
B. Virus
C. A eukaryotic animal cell
D.A eukaryotic plant cell
D.A eukaryotic plant cell

What is the primary function of the cell wall in plant cells?
To provide structural support and protection
400
In the animal cell shown, structure A is the site where what process happens?
Cellular Respiration
400
What is the primary difference between a tissue and an organ system?
an organs system is a collection of organism working together while many tissues can make up one organ and needs may organs to make a organ system
500
Which part of the cell theory explains how an injury on your skin eventually heals?
all cells come from pre-existing cells
Healing occurs because existing skin cells undergo division to create new, identical cells to replace the damaged ones.
500
Which of these is a characteristic shared by both prokaryotic and eukaryotic cells?
Cell membrane
500
What is the difference between a cell wall and a cell membrane?
The cell wall is just outside the cell membrane and is strong and rigid and only found in a plant cell
Cell membrane is flexible and lets certain material in and out
500
organelles that transport proteins in the cell.
Vesicles

D. Funal cell ( like mushroom or yeast)
D. Fungal Cell
they are consumer and do not perform photosynthesis BUT still have a cell wall.
