Describe the mutation in a plant that could have a negative outcome for the organism
iris [78.8K]
A mutation in a plant that could cause negative outcomes could be the plant has less leaves, or isn't hardy enough, like other plants. It would die. A plant from an area like Chernobyl, that has been affected by radiation could poison other animals, or pass that gene along, and ultimately kill that strand of plant.

<u>Chloroplast</u> - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

<u>Bryophyte</u> - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

<u>Pterophyte</u> - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

<u>Gymnosperm</u> - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

<u>Cone</u> - A cone-shaped flower head of various plants like banksias and proteas.

<u>Xylem</u> - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

<u>Phloem</u> - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

<u>Roots</u> - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

<u>Root hairs</u> - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

<u>Stems</u> - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

<u>Leaves</u> - The green and flat organ that represents the most prominent feature of the most vegetative plants.

<u>Photosynthesis</u> - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).
