Bacteria
Bacteria has a cell wall. Is that similar to a plant cell or an animal cell?
Plant cell
What does "pseudopod" mean?
"False feet"
When a virus invades a cell, what eventually happens to the cell?
The cell bursts and dies.
Fungi usually grow in what kind of places?
Wet and dark
What is the difference between sexual and asexual reproduction?
Sexual reproduction needs two parents.
Asexual reproduction needs one parent.
Bacteria are often unicellular. What does that mean?
They usually exist as one-cell organisms.
Plant-like protists are autotrophs or heterotrophs? Explain.
They are autotrophs because they can make their own food like plants.
Why can viruses spread so quickly?
Because millions of them could be made in one cell and spread about.
What do fungi make to reproduce?
Spores
Are plants autotrophs or heterotrophs? Explain.
Autotrophs. They can make their own energy using chloroplasts.
What are the three main shapes of bacteria?
Spherical, Rod, and Spiral.
Some protists are multicellular. What does that mean?
They are made up of more than one cell.
Are virus living or nonliving? Explain the main reason.
Viruses are not living because: it is not made up of cells.
What are the two main parts of a fungi?
Hyphae and fruiting body
What is the difference between prokaryotes and eukaryotes?
Prokaryotes = have cells that do not have a nucleus
Eukaryotes = have cells that have a nucleus
Are bacteria prokaryotes or eukaryotes? Do they have genetic material like DNA?
Bacteria are prokaryotes because they do not have a nucleus. However, they have genetic material but they are just spread about in the cell and not in a nucleus.
What are the three things that animal-like protists have that allows them to move around. Describe each one.
Flagellum - like a tail/tongue that rotates
Pseudopod - acts like a leg/foot that extends out
Cilia - lots of little hair
Can a virus reproduce on its own? What does it need?
Virus always needs another cell to reproduce because it cannot do it on its own. It invades other cells, takes over their nucleus to make more viruses.
Fungi are decomposers. What does that mean?
They are "nature's recyclers" because they break down chemicals in dead things. Without them, the world will be covered with dead things!
What is the difference between an autotroph and a heterotroph?
Autotroph = make own food
Heterotroph = feed on other things because cannot make their own food
Explain the steps for how a bacteria reproduces through binary fission.
Bacteria makes a copy of its genetic material --> Bacteria grows bigger --> Bacteria starts to split --> Two daughter cells are made
Animal-like protists are autotrophs or heterotrophs? Explain.
They are heterotrophs because they have to move around to find food to feed on.
Explain the steps for a virus invading a cell to reproduce itself.
Virus attaches to host cell --> Virus enters the cell --> Virus releases its genetic material --> The virus’ genetic material instructs the cell to produce materials to make new viruses --> New viruses are made inside the cell --> The cell bursts and releases the viruses.
Describe the steps for how a fungi feeds.
How are budding and binary fission similar?
They are both ways of reproducing where one cell splits into two daughter cells that are identical to the parents.
