Asexual vs. Sexual Reproduction Reinforcement (51 points) 1. Compare and contrast asexual reproduction and sexual reproduction. (2pts) Asexual: Occurs when offspring are produced from a single parent Advantageous in stable conditions Offspring are genetically identical to their parent (clones) Sexual: Occurs when offspring are produced by the joining of two haploid cells from two different parents Advantageous in changing conditions 2. What are six types of asexual reproduction? (2pts) Mitosis

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

PLANTS Plants in Our Daily Life A plant(also called green plants) is a multi-cellular living organism‚member of kingdom Plantae.It is at the base of the food web and are Autotrophs.Plants are considered as backbone of all life on Earth and essential resource for living oragnisms.Plants can be reffered as a factory which processes light into energy and manufactures food for it ownself as well as for other living things.Scientists have foundmore than 270‚000 spieces of plants They include a host of

3. Explain how the products of photosynthesis are transported‚ partitioned and allocated during plant growth and reproduction. Photosynthesis has been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process‚ similar to respiration and fermentation‚ in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Reproduction Research Assignment Sac 5 PART 1 : Asexual vs. Sexual Reproduction [ 4 marks ] - Discuss the differences between‚ and the advantages and disadvantages of sexual and asexual reproduction : SEXUAL REPRODUCTION Sexual Reproduction is the formation of a new organism from two parents usually‚ and involves the joining of gametes [ e.g. sperm‚ pollen‚ egg] to form a single cell called a zygote [ or fertilised egg ]. The offspring are similar‚ but not identical to the parents. Sexually Reproductive

Parthenogenesis vs. Sexual Reproduction Jorge Pablo Velasco Borda Introduction: Parthenogenesis is a type of reproduction in which the sperm does not fertilized the ovum. In parthenogenesis some chemical agents fertilize the ovum most of times because the female does not have a male to have sex with. That’s the case of Flora a Komodo dragon that live at the Chester Zoo in England (Chiang. M). Flora gave birth to seven babies without having a male. Sexual reproduction is when a sperm fertilize

Offspring are identical replicas of parent. Cell divides after DNA is replicated. No gametes are formed‚ can also occur by fragmentation (a piece of the organism breaking off) | Meiotic division. 2 parents are required. Each parent contributes ½ of the genetic

surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton to evolve. Then the evolutionary pace picked up. It took only 60 million years for plants radiate from the swampy lowlands to high mountains and nearly all places in between. They did so through modifications in
