Coniferophyta Division The Coniferophyta Division is made up of mostly evergreen trees and shrubs. These plants tend to be tough and can survive in stressful environments‚ including drought‚ high winds‚ heat‚ and cold. Some Conifers are the oldest plants on earth‚ growing to over 5‚000 years old. Conifers have either needles or scale-like leaves. They bear cones instead of fruits‚ and their seeds do not have a shell-like outer coating like flowering plants. Plants from the Coniferophyta Division

Biology form 4 – Chapter 5 Mitosis Mitosis is a division of the nucleus to produce two new daughter cells containing chromosomes identical to the parent cell. Significance of mitosis Growth- allows a zygote to produce more cell in order to grow Repair and replacement- allow the multicellular organism maintain its tissues‚ example skin cells and blood Asexual reproduction- clone The cell cycle divided into two major phases a. Interphase b. Mitosis Interphase is the period between division‚ divided

Dicot roots have X-shaped xylem whereas monocots are organized into a ring 3. Dicot stem xylem form a ring around the outside whereas monocot xylems are scattered 9.1.3 Distribution of tissues in leaves and functions In the leaf you have xylem and phloem tissues.

described the definition in On the Origin of Species. What is different about this and the modern view is that instead of a geographic barrier situation (allopatry)‚ there’s several other different types like reproductive barriers: both pre- and post-zygote‚ parapatric speciation‚ peripatric‚ and sympatric. The last three are reproductive barriers in their own right after the diverged species and the parent species re-meet. So‚ while Darwin got the geographic barrier part right‚ he missed another part:

barriers impede mating between species or hinder the fertilization of ova if members of different species attempt to mate. If a sperm cell from one species does fertilize an ovum of another species‚ then postzygotic barriers usually prevent the hybrid zygote from developing into a viable‚ fertile adult. 27. Discuss several prezygotic and post zygotic isolating mechanisms. Prezygotic Barriers Habitat Isolation. Two species that live in different habitats within the same area may encounter each other

However‚ such discussions are crucial to setting policies that balance individual and public protections with the use of technology in medicine.
