Rebecca has cystic fibrosis. Her body is unable to control the salt going into and out of her cells. Which organelle of Rebeccas cells is affected and unable to control what goes in and out of her cells?
Cell Membrane.
What are the 3 types of passive transport and explain them all. Do they require energy?
osmosis
diffusion
facilitated diffusion
no energy
What is the Nucleus?
It is the largest organelle in the cell and the command center. It directs the cell's activities.
What organisms are composed of cells?
ALL!
What is the thick, clear, gel-like fluid that holds all the organelles in a cell?
Cytoplasm.
Mosaic viruses cause plant leaves to look like mosaic art. A mixture of dark and light green patches show up on the leaves. The dark green patches are not able to capture much energy from the sunlight. Which organelle is affected by this virus? What organelle cannot capture energy from sunlight?
Chloroplasts.
What are the 3 types of passive transport and explain them all. Do they require energy?
endocytosis
exocytosis
yes energy
What is the function of the Chloroplasts?
Makes food for the plant cell using energy from sunlight. Photosynthesis.
Complete the sentence. Different cells work together and preform different.........? Why?
Functions. Because there are many different types of tissues that make up the body and have different functions to help the body run smoothly
Why do cells look different from each other?
Different cells specialize in different functions.
Joe's cells cannot convert food energy effectively into energy they can use. As a result, he gets extremely tired, has weak legs, and can't breathe well. Which organelle is affected by Joe's disease, and cannot convert food energy into energy?
The Mitochondria.
What does selectively permeable mean? Why does a cell membrane need to be selective?
lets only certain substances in or out of the membrane.
What two organelles are found in a plant cell, but not an animal cell?
Chloroplasts and Cell Wall.

schleiden and schwann concluded after many observations that all plants and animals are made of cells.
scientist had very little idea of the structure of organisms
Leeuwenhoek and Hooke used microscopes to observe cells in dead plants and tiny organisms in water
Electron microscopes enabled scientist to see cells in great detail
