What does ER do in plant and animal cells?

The organelle called 'endoplasmic reticulum' occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins. Many of these products are made for and exported to other organelles.

What does ER in a plant cell do?

The endoplasmic reticulum (ER) is the port of entry of proteins into the endomembrane system, and it is also involved in lipid biosynthesis and storage. ... This compartment is involved in cell to cell communication via the plasmodesmata, and, in specialized cells, it serves as a storage site for proteins.

Do plant and animal cells have a er?

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

What does the smooth ER do in a animal cell?

smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular ...

Why is the rough ER important?

The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Rough ER is the organelle that reads the DNA instructions to make the proteins. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus.

Do both plant and animal cells have mitochondria?

Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. ... Plants and animals are very different on the outside as well as on the cellular level. Both animal and plant cells have. mitochondria, but only plant cells have chloroplasts.

Is the rough ER in plant and animal cells?

There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.

What organelle does smooth ER work with?

The vesicles often move to the Golgi apparatus for additional protein packaging and distribution. Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids. Steroids are a type of ringed organic molecule used for many purposes in an organism.

What is the structure of ER?

The ER consists of the nuclear envelope and the peripheral ER, which includes smooth tubules and rough sheets. While the ER is defined as an interconnected network with a continuous membrane, the different structures that make up the ER perform very diverse and specialized functions within the cell.

What is the function of sER?

sER is a membrane-bound network of tubules (see Figs. sER is not involved in protein synthesis. ... Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.

Why is the ER considered the circulatory system of the cell?

It's analogous to the circulatory system in the body. The endoplasmic reticulum transports materials from one part of the cell to another, like the circulatory system in the body. Ribosomes manufacture proteins and send them to parts of the cell where they are needed.

How does the rough ER help ribosomes?

Rough ER is a host for ribosomes that continually attach to and detach from the ER surface. Essentially, the endoplasmic reticulum and ribosomes work together in order to synthesize proteins and have them transported to their final destination.

Why do plants need both chloroplasts and mitochondria?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

What does Animals cells have that plant cells don t?

Plant cells have a cell wall, but animals cells do not. ... Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.

How do plant and animal cells differ from lab answers?

Plant cells have a rigid cell wall, and if they are green, they also have chloroplasts. Animal cells lack both a cell wall and chloroplasts. They also lack the central vacuole common to plant cells. You will observe and compare animal cells and plant cells.

What does rough ER contain?

Rough endoplasmic reticulum is an organelle found in eukaryotic cells. Its main function is to produce proteins. It is made up of cisternae, tubules and vesicles. The cisternae are made up of flattened membrane disks, which are involved in the modification of proteins.

Do plants have smooth ER?

The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. ... It is described as 'smooth' to distinguish it from rough ER, which has ribosomes for protein synthesis on its surface.

What happens if the smooth ER malfunctions?

A malfunction of the ER stress response caused by aging, genetic mutations, or environmental factors can result in various diseases such as diabetes, inflammation, and neurodegenerative disorders including Alzheimer's disease, Parkinson's disease, and bipolar disorder, which are collectively known as 'conformational ...
