Explanation

Xylem and Phloem are specialized conducting tissues in vascular plants:

Xylem: Transports water and minerals from roots to other parts (unidirectional).

Phloem: Transports sugars (photosynthates) from leaves to other parts (bidirectional).

Explanation

Explanation

Poaceae, also called Gramineae

It is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses

Explanation

Haustoria are specialized structures produced by parasitic fungi.

They penetrate the host cells and absorb nutrients directly from the cytoplasm. 

Explanation

 Sweet peas are annual climbing plants with fragrant, butterfly-shaped flowers. 

They are part of the genus Lathyrus within the Fabaceae family. 

The name Lathyrus is derived from the Greek word for "pea," and odoratus means "scented". 

They are cultivated for their beautiful and fragrant flowers.

Explanation

Bacteriophages are significantly smaller than the bacteria they infect, meaning the volume of a phage is roughly 1/1000 of the host cell's volume. 

Explanation

In angiosperms (flowering plants), the endosperm is a triploid (3n) tissue that provides nourishment to the developing embryo.

It is formed during double fertilization, where one sperm nucleus fuses with the egg cell to form the zygote, and another sperm nucleus fuses with two polar nuclei in the embryo sac to create the triploid endosperm.

This triploid nature is a key characteristic of angiosperms and distinguishes them from gymnosperms, where the endosperm is haploid. 

Explanation

Gymnosperms are plants with exposed seeds, and Gingko is a well-known example of this type of plant. 

Explanation

Within the ovule of Pinus, a megaspore mother cell undergoes meiosis, resulting in the production of four haploid megaspores.

However, only one of these megaspores survives and develops into the female gametophyte. 

Explanation

The exchange of parts of non-sister chromatids of homologous chromosomes during meiosis is called Crossing over. 

During meiosis, homologous chromosomes pair up and "cross over," exchanging genetic material between their non-sister chromatids, resulting in new combinations of alleles.
