What is the shape of the chloroplast?

Chloroplasts are a type of plastid—a round, oval, or disk-shaped body that is involved in the synthesis and storage of foodstuffs. Chloroplasts are distinguished from other types of plastids by their green colour, which results from the presence of two pigments, chlorophyll a and chlorophyll b.

Chloroplasts are found in all higher plants. It is oval or biconvex, found within the mesophyll of the plant cell. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. They are double-membrane organelle with the presence of outer, inner and intermembrane space.

What is the shape of Ulothrix?

Class: Chlorophyceae Wille in Warming, 1884

What is the shape of chloroplast in 36?

The shape of chloroplast in higher plants is discoid.

Does Ulothrix have chloroplast?

They are Eukaryotic and multicellular because the cells have specific functions as the lowermost cell serves as holdfast and it doesn’t have chloroplast, and the apical cell is dome-shaped. The genus includes: Ulothrix aequalis Kützing. Ulothrix moniliformis Kützing.

Is Oedogonium unicellular or multicellular?

Oedogonium, genus of filamentous green algae (family Oedogoniaceae), commonly found in quiet bodies of fresh water. They often are attached to other plants or exist as a free-floating mass. Oedogonium filaments are typically unbranched and only one cell thick.

What is the shape of each cell of spirogyra?

Spirogyra filaments are straight, uniseriate, and unbranched. The cells are longer than broad and each contain at least one and as many as sixteen spiraled, ribbon-shaped, parietal chloroplasts with numerous round pyrenoids.

Do diatoms have chloroplasts?

Diatom Chloroplast Structure and Genomes

Diatoms and other photosynthetic members of the stramenopile algae possess a chloroplast derived from the secondary endosymbiosis of a red alga (Figure 2a).

How many chloroplasts are in a spirogyra cell?

In each cell, there is a nucleus, cytoplasm, a large central vacuole and spiral chloroplasts. Chloroplasts are ribbon-shaped and arranged spirally. There may be 1-16 chloroplasts present in a cell.

What structure is chloroplast?

Inside the chloroplast are stacks of thylakoids, called grana, as well as stroma, the dense fluid inside of the chloroplast. These thylakoids contain the chlorophyll that is necessary for the plant to go through photosynthesis. The space the chlorophyll fills is called the thylakoid space.

What is the structure of a Chromoplast?

Using a light microscope chromoplasts can be differentiated and are classified into four main types. The first type is composed of proteic stroma with granules. The second is composed of protein crystals and amorphous pigment granules. The third type is composed of protein and pigment crystals.

What is mitochondria shape?

A mitochondrion is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms. It produces energy, known as ATP, for the cell through a series of chemical reactions.

What is the shape of chloroplast present in Volvox?

Like Chlamydomonas, each spherical or ovoid cell has two equal flagella with a pair of contractile vacuoles at their base and a large cup-shaped chloroplast with a single pyrenoid.

What is discoid chloroplast?

Discoid. Discoid-shaped chloroplast is found in higher plants, whereas cup-shaped chloroplast is found in the green algae Chlamydomonas. Ulothrix has girdle-shaped chloroplasts and Chlorophyceae have reticulate chloroplasts. Biology.

What are girdles and scabbards?

What is the reproductive structure of Oedogonium?

Reproduction. Oedogonium reproduces asexually via mobile zoospores and sexually via sperm, oogonia and zygospores. Sperm are released from parental cells and are chemo-attracted to the oogonia that house an egg. A pore in the oogonium cell wall allows the sperm to enter the oogonium and fertilize the egg.
