Eukaryotic and Prokaryotic Cells
what are prokaryotic cells?
A prokaryote is a single-cell organism whose cell lacks a nucleus and other membrane-bound organelles.
whats a plant cell
Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.
whats an animal cell
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles.
This is the brain of the cell. It controls the cell's activities.
nucleus
Which of the following is NOT a cell structure used for locomotion by unicellular organisms?
cell wall
pseudopod
flagellum
cilium
cell wall
what are eukaryotic cells?
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms.
Why are plant cells so important?
Plant cells are the fundamental organizational unit that mediate production, transport, and storage of our primary food sources and sequester a significant proportion of the world's carbon.
why are animal cells important?
Some important functions of an animal cell include giving the animal's body its structure, absorbing nutrients to convert to energy, and helping animals move.
This is the jelly-like substance that holds and protects the cell's organelles.
cytoplasm
Which best explains how a single-celled organism can survive without other cells?
They do not need to perform more than one function to survive.
They are able to perform all necessary functions within one cell.
They do not need any substance from outside of the cell.
They are able to perform all necessary functions within one cell.
difference between prokaryotic and eukaryotic cell?
Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
What is the most important cell in a plant?
The most important part of a plant cell is the nucleus.
This is a large sac that holds food, water, and waste.
vacuole
Which best describes a single-celled organism?
a small group of organisms
an organism that is able to carry out all its life processes
a small organism with a variety of parts
an organism that relies on other organisms to survive
an organism that is able to carry out all its life processes
similarities between prokaryotic and eukaryotic cell
being alive, having a cell membrane, having DNA, ribosomes, and the ability to divide and reproduce.
What is absent in plant cells?
Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.
what is absent in an animal cell
Cell wall is absent in an animal cell.
These structures are known as the powerhouse of the cell because they release energy.
mitochondria
Logan is comparing the characteristics of different types of organisms. Which best describes a difference between insects and bacteria?
Insects are made of one cell, while bacteria are made of many cells.
Insects require energy to perform life functions while bacteria do not.
Bacteria are made of one cell, while insects are made of many cells.
Bacteria require energy to perform life functions while insects do not.
Bacteria are made of one cell, while insects are made of many cells.
what is a disease you can get from a eukaryotic cell
malaria
what are the cells found within plants
Plants have eukaryotic cells with large central vacuoles, cell walls containing cellulose, and plastids such as chloroplasts and chromoplasts.
What two things are found in animal cells but not in plant cells?
Centrioles and lysosomes are found only in animal cells and not in plant cells.
his structure packages and moves proteins through the cell.
golgi body
Which is a characteristic of bacteria?
large in size
found only in one particular environment
made up of many different cells working together
able to survive as a single cell
able to survive as a single cell
