Life Processes

Ulothrix and Spirogyra exist in filamentous form.

Leaf like photosynthetic organ in brown algae is known as frond.

Mannitol and laminarin are stored food products in brown algae.

All the above statements are correct.

Flagella are absent in red algae.

In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower and marigold.

Radicle is enclosed in a sheath called coleorhiza

Fabaceae; Inflorescence is racemose. Flower is bisexual, zygomorphic.

SER is the major site for synthesis of lipid.

In conjoint type of vascular bundles, the xylem and phloem are situated at the same radius of vascular bundles. Such vascular bundles are common in stems and leaves.

The peripheral region of the secondary xylem, is lighter in colour and is known as the sapwood. It is involved in the conduction of water and minerals from root to leaf.

Ribulose bisphosphate Carboxylase-Oxygenase (RuBisCO) is the most abundant protein in the whole of the biosphere.

The content of nucleolus is continuous with the rest of the nucleoplasm as it is not a membrane bound structure. It is a site for active ribosomal RNA synthesis.

Nuclear envelope assembles around the chromosome clusters and nucleolus, golgi complex and ER reform in telophase.

Elaioplasts store oils and fats.

Fucus, an alga is diplontic.

There are five petals, the largest (standard) overlaps the two lateral petals (wings), which in turn overlap the two smallest anterior petals (keel); this type of aestivation is known as vexillary.
