What can a cell wall be compared to?
The cell wall is like a bullet proof vest, because a cell wall protects the cell like a bullet proof vest protects its user. The cytoplasm is like a jello salad because the cytoplasm surrounds and suspends the cell’s organelles like the jello surrounds and suspends the fruit in the jello salad. 6.
What things can represent a cell?
Cell Analogy Household Cell
- Chlorplasts. (Solar Panel)
- Cytoplasm (Bag)
- Cell Wall (Plastic Container)
- Mitochondria (Battery)
- Vacuole (Contatainer)
- Ribosomes (Kapla)
- Endoplasmic Reticulum (Straw)
- Cell Membrane (Cardboard Box)
What everyday object is like a cell wall?
Analogy: The cell wall is like a storm shelter because the cell wall acts as if it is a protective barrier for the cell. A storm shelter helps protect people from storms and other dangers.
What food can represent cell wall?
Pick a light colored flavor (lime for plants, strawberry for animals). Every 6 oz package will make 4 or 5 “cells”….
| Cell Component | Suggested “Building Material” |
|---|---|
| Vacuoles | 4 chocolate covered raisins |
| Plant Cell central vacuole | 1 large white marshmallow |
| Nucleus | 1 pink gumball |
| Cell wall | a sheet of green fruit roll up |
What compares to a cell?
The quickest way to compare two cells is with a formula that uses the equal sign. If the cell contents are the same, the result is TRUE. (Upper and lower case versions of the same letter are treated as equal).
Why is the cell wall bad?
Damage to the cell wall disturbs the state of cell electrolytes, which can activate death pathways (apoptosis or programmed cell death). They also play an important role in the elimination of damaged cells, such as those irreversibly injured by environmental or antibiotic stress.
How a cell is like a house?
Cell organelle. A cell is like a house. While the nucleus is the control center of the cell, people control everything inside the house. The Golgi apparatus packages/delivers proteins.
How a cell is like a school?
The Cell Wall is like the beams in a school because it provides the school support. The Chloroplast is like the cafeteria in a school because it is where the students in a school get their energy. The Large Central Vacuole is like a swimming pool because it stores water for the swim team.
What is the main function of the cell wall?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What are the functions of the cell wall?
The plant cell wall serves a variety of functions. Along with protecting the intracellular contents, the structure bestows rigidity to the plant, provides a porous medium for the circulation and distribution of water, minerals, and other nutrients, and houses specialized molecules that regulate growth and pro… Loading…
How much of the cell wall does peptidoglycan represent?
In fact, peptidoglycan can represent up to 90% of the cell wall, with layer after layer forming around the cell membrane. The NAM tetrapeptides are typically cross-linked with a peptide interbridge and complete cross-linking is common.
What makes up the cell walls of Gram positive bacteria?
Gram Positive Cell walls. The cell walls of gram positive bacteria are composed predominantly of peptidoglycan. In fact, peptidoglycan can represent up to 90% of the cell wall, with layer after layer forming around the cell membrane. The NAM tetrapeptides are typically cross-linked with a peptide interbridge and complete cross-linking is common.
How are two types of cell walls identified?
The two different cell wall types can be identified in the lab by a differential stain known as the Gram stain. Developed in 1884, it’s been in use ever since. Originally, it was not known why the Gram stain allowed for such reliable separation of bacterial into two groups.
