Modified Leaf of a Plant

A modified leaf is a changed leaf that does task differently then a normal leaf. An example of this would be a cactus. Cactus live in the desert so they have to store water and protect themselves from danger. In order to do this they produce thorns on their leaves.


Rhizome

Rhizome is a under the ground stem that grow shoots and roots and stores starch. It is also known as ‘the creeping stalk.’ An example of a rhizome is a ginger root. The ginger grows from the rhizome root.

Parasitism

Parasitism is the process in which little vermin(parasites) feed off of other organisms in order to live . An example of this is a pupae and a fly. Female fly parasites lay eggs inside pupae and when they hatch the parasite larvae eats the inside of the fly pupae. They must find pupae in order to reproduce.

Sporophyte

A sporophyte is a plant that goes through the alternation of generations which in return makes asexual spores. An example of this is moss. Moss is a sporophyte because it goes through the process of a haploid(1n) alternating with a diploid(2n) which then goes through the meiosis stage and gets split in half. Coming out with one n chromosome in the end. All sporophytes go through the alternation of generations. 

Pollen

Pollen is the sperm of the anther(male plant) that is taken to the stigma(female plant) through various ways. It is what pollinates the stigma which in return produces more flowers.

Frond

A frond is a large leaf that is divided and an example of this would be a fern. Its leaves have the branching vein system and the fern leaves unravel from the croziers.

Spore

A spore is a reproductive cell that can grow without getting with another reproductive cell. An example of a spore would be a mushroom. The mushroom’s seeds are considered to be spores. Through these little spores, mushrooms are able to make more of their own without having to mate. Mushrooms grow above the ground.
