Organelles 1
These tiny organelles synthesize proteins by linking amino acids together.
What are ribosomes?
In a lab we put salt water on an onion cell, observed the difference in the cell, and then put fresh water on the cell. What process is happening?
osmosis
Plants use this process to make their own food
photosynthesis
This characteristic of the cell membrane allows some molecules in and keeps others out.
What is selective permeability (semi-permeability)?
What are the four types of macromolecules?
lipids, carbs, nucleic acids, proteins
What is the mitochondria?
What are Iodine and Benedicts Solution called? Why do we use them?
Indicators, they change color in the presence of glucose and starch so we can tell where the moved
These are the reactants in Cellular Respiration.
What is glucose and oxygen?
This type of transport involves water moving across a membrane from a high to a low concentration.
What is osmosis?
All living things are made up of............
cells
This organelle contains enzymes that cleans up and recycles worn out cell parts.
What is the lysosome?
What organelle is dialysis tubing acting like in our lab?
Cell membrane
These are the products of cellular respiration
carbon dioxide+ water+ATP
This movement requires energy
Active transport
Besides ATP, these are also products of cellular respiration.
What is CO2 and water?
This organelle is considered the "brain" of the cell and the control center.
nucleus
If we have a slide with red onion cells under a microscope and place salt water on the outside of the slide, what will happen to the red onion cells?
they will shrink, the water int he cells will diffuse out of the cell due to a lower concentration of water
What similarities do photosynthesis and cellular respiration have in common?
both use water, oxygen, carbon dioxide, atp, glucose but in different ways
both happen in living things/necessary for life
When a cell receives a balance of required nutrients and water, it is considered to be in this state.
What is homeostasis?
These are the two properties of the lipid bilayer and their relation to water.
What is hydrophobic and hydrophilic?
These two organelles can be found in plant cells but not in animal cells.
What is chloroplast and cell wall?
If we have dialysis tube filled with starch and glucose sitting in a container of iodine and Benedicts solution, why does the water change color on the outside of the tubing?
starch moves out of the dialysis tubing
what organelle is responsible for cellular respiration?
mitochondria
This process is the movement of high to low
diffusion
"All living things or organisms are made of cells" is apart of this widely accepted theory.
What is the cell theory?
