What part of the cell is labeled B?
AP Chapter 6 – Cells (basic)
| A | B |
|---|---|
| What is the structure labeled “B”?, | smooth endoplasmic reticulum (smooth ER) – notice the lack of ribosomes on the membrane folds, |
| What are the tiny structures labeled “C”?, | ribosomes, |
| What is the structure labeled “D”?, | central vacuole, |
| What is the structure labeled “E”?, | Chloroplast, |
What are the two labeled parts of the animal cell in the cell cycle?
The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.
What are the 2 cell groups?
There are two distinct types of cells: prokaryotic cells and eukaryotic cells.
What are the parts of animal cells?
There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
What are the parts and functions of animal cell?
Animal cells and plant cells
| Part | Function |
|---|---|
| Cell membrane | Controls the movement of substances into and out of the cell |
| Cytoplasm | Jelly-like substance, where chemical reactions happen |
| Nucleus | Carries genetic information and controls what happens inside the cell |
| Mitochondria | Where most respiration reactions happen |
What are parts of animal cell?
What is in a animal cell?
A cell (plasma) membrane encloses the cytoplasmic contents, such as the nucleus, peroxisome, cytoskeleton, lysosome, ribosomes, mitochondria, Golgi apparatus, centrosome, and endoplasmic reticulum. A typical structure of an animal cell includes organelles, cytoplasmic structures, cytosol, and cell membrane.
What is the specific role of the enzyme indicated by B during the formation of the new DNA strands?
What is the specific role of the enzyme indicated by B during the formation of the new DNA strands? DNA polymerase catalyzes formation of bonds between sugar groups and phosphate groups that link the DNA nucleotides together.
Which of the following events might the solid arrow at the bottom of B represent?
Which of the following events might the solid arrow at the bottom of B represent? the activation of specific cytoplasmic enzymes: Once activated by the binding of a specific chemical messenger, such as a hormone, the receptor initiates cellular responses by activating specific signal transduction pathways.
What are the parts of the animal cell and its functions?
What type of cell is D?
Delta cells (δ-cells or D cells) are somatostatin-producing cells. They can be found in the stomach, intestine and the pancreatic islets. Delta cells comprise ca 5% of the cells in the islets but may interact with many more islet cells than suggested by their low numbers.
What are the 2 main types of cells What is the main difference between the 2 types?
There are only two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles. Eukaryotic cells have a nucleus and other membrane-bound organelles. This allows these cells to have complex functions.
What are the 9 parts of an animal cell?
A cell (plasma) membrane encloses the cytoplasmic contents, such as nucleus, peroxisome, cytoskeleton, lysosome, ribosomes, mitochondria, Golgi apparatus, centrosome, and endoplasmic reticulum. A typical structure of an animal cell includes organelles, cytoplasmic structures, cytosol, and cell membrane.
How many cells are in an animal cell?
Overview of Animal Cells Animals, plants, fungi, and protists are all made up of at least one eukaryotic cell. In contrast, bacteria and archaea are made up of a single prokaryotic cell. All cells are surrounded by a cell membrane (also called a plasma membrane).
What are the different shapes of animal cells?
The shape of animal cells also varies, with some being flat, others oval or rod-shaped. There are also more intriguing shapes such as curved, spherical, concave and rectangular.
What is the combined effort of all animal cells?
Generally, the combined effort by all animal cells is what enables the normal functioning of the body. It is a thin semipermeable protein-membrane layer that surrounds an animal cell.
What is the genetic material of an animal cell?
As noted earlier, animal cells are eukaryotic cells with a membrane-bound nucleus. therefore they have their genetic material in the form of DNA enclosed in the nucleus.
