Is a smooth er a plant or a animal or both?

Definition of the Smooth ER The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.

Is smooth ER in plant and animal cells?

SER occurs both in animal and in plant cells.

Do both animal and plant cells have 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.

Where is the smooth ER located in a plant cell?

Rough endoplasmic reticulum(RER) found mainly toward the nucleus of cell and smooth endoplasmic reticulum(SER) found towards the cell membrane or plasma membrane of cell. The outer (cytosolic) face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis.

Where is the rough ER in a animal cell?

Rough ER lies immediately adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope. The ribosomes on rough ER specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the ER for processing.

What is smooth ER in plant cell?

The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. ... The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism.

What is the smooth ER made of?

The smooth endoplasmic reticulum is primarily composed of three-dimensional polygonal networks of tubules called cisternae. They are about 50 nm in diameter in mammals and 30 nm in diameter in yeast.

Do both plant and animal cells have mitochondria?

Furthermore, it is no surprise that mitochondria are present in both plants and animals, implying major shared regulatory, bioenergetic, and chemical substrate pathways. Commonalities of energy processing in both plants and animals have become even stronger by the finding that chloroplast can be found in animal cells.

How does the smooth ER make lipids?

The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. ... In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.

Which of these things do both plant and animal cells have?

Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.

What are the function of ER?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

What organelles does smooth ER work with?

While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.

What is the difference between rough and smooth ER?

The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.

Is rough ER in plant and animal cells?

The ER performs multiple functions in both plant and animal cells. ... Rough and smooth ER are typically connected to one another so that the proteins and membranes made by the rough ER can freely move into the smooth ER for transport to other parts of the cell.

Do both animal and plant cells have chloroplast?

Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. ... For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.

Do animals have endoplasmic reticulum?

The endoplasmic reticulum (ER) in animal cells is an extensive, morphologically continuous network of membrane tubules and flattened cisternae.
