What's the difference between multi cellular and unicellular?
Multi cellular= More than one cell
Uni cellular= One celled
Cell Membrane
Decided what enters and exits the cell
Ex: window screen
What occurs in the two different stages of photosynthesis?
Organisms obtain the sun's energy and converts it from carbon dioxide and water to oxygen and sugar.
Explain Interphase
- Cell grows to full, mature size
What is it called when the inside and outside of the cell has an equal proportion of concentration?
Isotonic Solution
Define Prokaryote and Eukaryote
Prokaryote= Organisms whose cells lack a nucleus.
Eukaryote= Organisms whose cells contain a nucleus.
Cell wall
Protects and supports the cell.
Where specifically in a plant does photosynthesis take place?
In the chloroplast
What happens during Mitosis: Prophase
- Copied DNA condenses into chromosomes
What is it called when the concentration of molecules inside the cell is less then outside the cell?
Hypertonic
What is Mitosis?
The nucleus and its contents divide, forming two identical cells.
Golgi Body
Receives proteins and other materials from the ER, packages them, and distributes them to other parts of the cell.
What stage of respiration releases most of the energy in glucose?
Second Stage- Mitochondria
Explain Mitosis: Metaphase
- Chromosomes line up across center of cell
If a red blood cell has lost so much water it shrivels it's a solution of ______________.
Hypertonic
Define Chromosome
A piece of DNA covered with genes.
Mitochondria
Converts energy in food molecules to energy the cell needs to perform its functions.
What happens during respiration?
Cells break down food molecules like sugar and release the energy they contain.
List an event that occurs during Mitosis:Anaphase
- Centromere split
When there is a higher concentration of molecules inside the cell that outside the cell.
Hypotonic
Respiration
A system in which cells acquire energy from glucose.
Endoplasmic Reticulum
A maze of passageways that deliver proteins and materials to other places.
Together, respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere ____________.
Constant
List an event that takes place in cytokinesis
- Cytoplasm divides organelles distributed into two new cells.
If red blood cell remains in its normal condition and has reached homeostasis this is because of _______
Isotonic
