L1: Structure and Function of Cells
The "building blocks" of life
Tiny cell structures that carry out a function inside the cell.
Organelles
A "balanced" internal environment.
Homeostasis
Say the full name of DNA.
Deoxyribonucleic Acid
Nearly all living organisms obtain energy either directly or indirectly from the ________.
SUN
These organisms can't make their own food; they eat other organisms.
Heterotrophs
What does "CYTE" mean?
Cell
This organelle gives protection and support to the cell.
Cell Wall
The movement of particles from a HIGH to a LOW concentration
Diffusion
What are the 3 stages of Cell Division?
1. Interphase
2. Mitosis
3. Cytokinesis
What is the chemical formula for glucose? Be sure to include the exact number of each type of atom.
C6H12O6
The 2 organelles that cellular respiration occurs...
List at least 3 of the 6 functions of cells.
1. Bringing in nutrients and water
2. Obtain (get) energy
3. Getting rid of waste
4. Grow and repair
5. Respond to surroundings
6. Reproduce
This is the "Amazon" of the cell.
(it packages and ships proteins and other molecules)
Golgi Apparatus
This type of passive transport happens when water molecules move across a selectively permeable membrane from from a HIGH to a LOW concetntration.
Osmosis
This form or shape of DNA is condensed; ½ of the X
Chromatids
During Photosynthesis, CO2 enters the plant through a small opening called the ______________.
stomata
__________ ____________ is produced in muscles after running fast or for a long time. It releases a small amount of energy and causes the "burning" sensation.
Lactic acid
Humans, animals, insects, etc...
This is the organelle known as the “builder” (or factory) of proteins because it assembles amino acids into proteins.
Ribosomes
The passive movement of material through a protein channel in the cell membrane.
Facilitated Diffusion
During this phase of mitosis, the centrioles send out spindle fibers that pull the sister chromatids apart.
Anaphase
What is the product of the second stage of Photosynthesis?
C6H12O6
Which types of organisms perform cellular respiration? Autotrophs, heterotrophs, or both?
BOTH
One example of a prokaryotic cell
Amoeba, bacteria, yeast, paramecium
This organelle converts light energy into chemical energy by photosynthesis.
Chloroplast
Which type of cell transport moves particles from a low concentration to a high concentration, into or out of the cell?
Active Transport
During what stage is DNA replicated (identical copy made)?
Interphase
___________ is a green pigment that absorbs light.
Chlorophyll
What does "ANAEROBIC" mean?
Without oxygen
The Cell Theory is made up of three main points. What are they?
1. All living things are made of cells
2. Cells are the basic units of structure and function in living things
3. Cells come from cells
What organelle pulls chromatids apart?
Centriole
In a solution of lemonade, what is the solute?
Powder
What is the name of the structure that holds sister chromatids together?
Centromere
What are the raw materials of photosynthesis?
CO2 and H2O
What are the products of cellular respiration?
CO2 and H2O and ENERGY!
