Where is nucleus in Elodea cell?

Where is nucleus in Elodea cell?

The green dots are chloroplasts. Notice the colourless space – the vacuole – in the middle of the cells. The nucleus appears to be hidden (between the chloroplasts?)….Approximate sizes:

Why can’t you see the nucleus in an Elodea cell?

The nucleus is present but not visible, particularly in an Elodea cell, because the cell membrane is thin, transparent, and in direct contact with the…

Does an Elodea cell have cytoplasm?

The flat, cuboidal leaf cells of Elodea contain a relatively large central vacuole surrounded by a thin layer of cytoplasm.

Do plant cells have a nucleus?

Plant cells, like animal cells, are eukaryotic, meaning they have a membrane-bound nucleus and organelles.

Is Elodea cell prokaryotic or eukaryotic?

eukaryotic cells
We will also observe a variety of eukaryotic cells, including examples of protists (Paramecia), plant cells (Elodea and onion) and animal cells (human epithelial cells). Typically, eukaryotic cells are much larger and more complex than prokaryotic cells.

Do prokaryotes have a nucleus?

Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

What structures were only visible in the Elodea cells?

Onion and Elodea (Cabomba) are both plants, yet chloroplasts are only visible in the Elodea cells.

What kind of cell contains a nucleus mitochondria and chloroplasts?

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.

Which cell has no nucleus?

Prokaryotes
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Which plant cells do not have a nucleus?

There are many parts of plant which do not contain nucleus: Sclerenchymatous cells get deposited by lignin and lose nucleus & cytoplasm at maturity. Xylem vessels consist of series of elongated dead cells for quick conduction of water and salts. Sieve tubes which also conduct food, don’t have nucleus in them.

Is Elodea single celled?

The Elodea plant is an organism. It is made of many cells and it is a multicellular organism.

Which of the following lacks nucleus?

Prokaryotic cells
Which of the following lacks a nucleus? Explanation: Prokaryotic cells do not have a nucleus. The genetic material for prokaryotes is concentrated in a region called the nucleoid but there is no membrane separating this region from the rest of the cell unlike in eukaryotic cells, which do have membrane-bound nuclei.
