Do spirogyra have cell wall?
Yes, spirogyra have a cell wall. The cell wall of spirogyra is made up of cellulose and provides structural support and protection to the cell.
What happens when plasmolysed spirogyra filament is put in water?
When a plasmolysed Spirogyra filament is put in water, it will undergo the process of deplasmolysis. The cell will reabsorb the water, causing the cytoplasm to expand and push the cell membrane against the cell wall. The cell regains its turgidity and returns to its original state.
What are all the parts of spirogyra?
Spirogyra is a type of filamentous green algae consisting of cells arranged end to end to form long, thread-like filaments. Each cell has a central vacuole, a nucleus, and spiral chloroplasts. Spirogyra also has two types of reproductive cells: isogametes and zygospores.
Does spirogyra plant have stems root and leaves?
No, Spirogyra is a type of filamentous green algae that does not have traditional plant structures like stems, roots, and leaves. Instead, Spirogyra consists of long, unbranched filaments made up of cells containing chloroplasts for photosynthesis.
Are spirogyra multicellular or colonial algae?
Spirogyra is a multicellular filamentous green algae. Each cell is connected end-to-end to form long chains or filaments.
Do spirogyra have cell wall?
Yes, spirogyra have a cell wall. The cell wall of spirogyra is made up of cellulose and provides structural support and protection to the cell.
Why is spirogyra slimy to touch?
In spirogyra the outer cell wall is made up of pectin which dissolves in water and gives slimy appearance.
How can can plasmolysis be demonstrated in the laboratory using a filament of spirogyra?
To demonstrate plasmolysis with a filament of spirogyra in the laboratory, place the filament in a hypertonic solution such as salt water. As water leaves the cell by osmosis, the cytoplasm shrinks away from the cell wall, leading to the detachment of the cytoplasm from the cell wall, demonstrating plasmolysis. This can be observed under a microscope.
What happens when plasmolysed spirogyra filament is put in water?
When a plasmolysed Spirogyra filament is put in water, it will undergo the process of deplasmolysis. The cell will reabsorb the water, causing the cytoplasm to expand and push the cell membrane against the cell wall. The cell regains its turgidity and returns to its original state.
What prevents desiccation or drying up in spirogyra?
Spirogyra has a gelatinous sheath around its cell wall that helps retain water, preventing desiccation. Additionally, the presence of a large central vacuole stores water that can be used during dry periods, ensuring hydration of the cell.
What are all the parts of spirogyra?
Spirogyra is a type of filamentous green algae consisting of cells arranged end to end to form long, thread-like filaments. Each cell has a central vacuole, a nucleus, and spiral chloroplasts. Spirogyra also has two types of reproductive cells: isogametes and zygospores.
What does the nucleus hang by in a spirogyra cell?
The nucleus in a spirogyra cell is suspended by thin strands of cytoplasm called cytoplasmic strands. These strands help anchor and position the nucleus within the cell.
How do substances move into cells in spirogyra?
Substances in Spirogyra move into cells through a process called passive diffusion. Spirogyra cells have a cell wall made of cellulose that is freely permeable to water and dissolved substances. This allows nutrients and waste to move in and out of the cells easily.
Where can you find spirogyra cell?
in africas jungle savannahs
Why do all cell in a spirogyra filament look different?
no no
Is spirogyra an example of a single celled alga?
No, Spirogyra is a filamentous freshwater green algae, meaning it is multicellular. Each individual cell in Spirogyra is connected to form long chains or filaments.
Does spirogyra plant have stems root and leaves?
No, Spirogyra is a type of filamentous green algae that does not have traditional plant structures like stems, roots, and leaves. Instead, Spirogyra consists of long, unbranched filaments made up of cells containing chloroplasts for photosynthesis.
