Question

Define (a) Photic Region (b) Phycocolloids (c) Kelps (d) Moss (e) Ovule

Answer 1

Hint:- Most marine life finds shelter within the photic region also referred to as the photic zone. Plasma membranes of algae contain Phycocolloids. Despite the looks, kelp doesn't belong to Plantae.

Complete Answer:-Photic Region: The top most region of sea is termed as the Photic region. It allows photosynthesis to phytoplankton and plants due the availability and heavy influence of sunlight. The nutrient concentration has been observed low in the region due to the fast uptake of nutrients plants during photosynthesis.
Phycocolloids: The term Phycocolloids refers to the polysaccharides obtained from seaweed. They form colloidal suspension in water and are derived from algae. They are known for their multiple applications in cosmetic and pharmaceutical industries. They are often used as a food source.
Kelps: Kelps are highly nutritious large brown Algae. They are a type of coastal seaweeds which grow in the cold Shallow Ocean. They are full of iron, potassium, calcium and other nutrients and so are widely used for commercial purposes.
Moss: Moss belongs to division Bryophyte. They’re non-vascular spore producing plants. The plant body is formed from stem like, leaf like and root like i.e. rhizoid. The expansion rate of mosses is extremely slow and similar to plants, they utilise sunlight to perform photosynthesis.
Ovule: In higher plants, Ovule represents the feminine organ. It will be termed as an immature seed containing megasporangium. It also consists of nucellus and integuments. It develops on the ovarian wall and matures to make seed in flowering plants.

Note:- Kelp ash is thought to be rich in Iodine and alkali. It’s been employed in the treatment of Goitre thanks to its high Iodine concentration. It’s commercially employed in the assembly of glass and in soaps. It’s also produced as a food source.
