Through a division process called mitosis, eukaryotic cells divide to create new cells. It enables cell replacement after damage or wear-and-tear and also permits growth.

Mitosis is the process of cell division in which the chromosomes replicate and are evenly dispersed into the two daughter cells. It specifically refers to the division of the duplicated genetic material held in the nucleus during cell division. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. So, meiosis is the process where a single cell divides twice to produce four cells with half the original amount of genetic material. Mitosis is known as equational division. These cells are our sex cells, producing sperm in males and eggs in females throughout the process of mitosis. Eukaryotic cells go through the nuclear division process known as mitosis when they divide to produce two identical daughter cells.

Why cycus are called conifer? give its 3major characteristics features​
Licemer1 [7]

Answer:

Cycads /ˈsaɪkædz/ are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, therefore the individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly[3] and live very long, with some specimens known to be as much as 1,000 years old.[citation needed] Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.

Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones.

Cycads have been reported to fix nitrogen in association with various cyanobacteria living in the roots (the "coralloid" roots).[4] These photosynthetic bacteria produce a neurotoxin called BMAA that is found in the seeds of cycads. This neurotoxin may enter a human food chain as the cycad seeds may be eaten directly as a source of flour by humans or by wild or feral animals such as bats, and humans may eat these animals. It is hypothesized that this is a source of some neurological diseases in humans.[5][6]

Cycads all over the world are in decline, with four species on the brink of extinction and seven species having fewer than 100 plants left in the wild.[7] The plant has a very long fossil history, with evidence that they existed in greater abundance and in greater diversity before the Jurassic and late Triassic mass extinction events.

Answer:

Bisexual flowers:

In order to make a new seed male gamete present in a pollen grain units with the female gamete present in the ovule.

Unisexual flowers:

Unisexual flower can self pollinate where both male and female flowers are present on the same plant. Stigma of the female flower can be pollinated by the pollen of the male flower present on the same plant.
