Biodiversity Mind Map Assignment

it's a prokaryote (lacking nuclei) - single celled, no membrane bound organelles, smaller & less complexCoccus - sphericalBacillus - rod-likeSpirillum - spiral

it's a prokaryote - single celled, no membrane bound organelles, smaller & less complex some live in extreme environmentsextremely hotchemically abrasive

it is eukaryotic - contain membrane bound organelles, complex structures

Characteristics aquatic diverse in structure could be heterotrophic (can make their own food) or Autotrophic (can't make their own) Motile (use, pseudopods, cilia or flagella Unicellular Complex w/ many organelles Reproduce both ace/sexually

use pseudopods to move (blob-like and very slow)

They have cilia (tiny & hair like) that beat in order to move (in a propelling motion)

they have a flagella (tail-like and moves fast like)

no pseudopod, cilia or flagella they invade or get eaten by hosts which helps distribute them

photosynthesize - its why they're plant like

saprophytic heterotrophs - (digest externally & then absorb food)

characteristics chemoheterotrophic - can't produce their own food: absorb it reproduce using spores a/sexual usually not motile Alternation of generation cell wall are made up of chitin

Common Molds Conjugated - a/sexual -asexual , spores are released Sexual , zygote is formed

Sac fungiasexual , fragmentationSexual , zygote is formed

Club Fungisexually - zygote is formed

Imperfect Fungiasexual - spores are released

chytridsa/sexualspores alternation of generations

defining characteristics include:multicellularPhotosynthetic - contain chlorophyl a & bAlternation of generations - change btwn haploid & diploid state Develop from embryos - product of sexual fusion

chlorophyll a & b = green colour = better photosynthesis

Characteristics they've have adapted to moist environmentsLack vascular tissueadaptation smaller/shorter = more efficient when moving nutrients throughout the plant

Characteristics Vascular structures allow them to grow larger, survive in habitats that may not have water readily availableas they are able to transport the nutrients throughout the plant (Xylem & Phloem)

Characteristics leaves have reduced surface area (needles)when temp. decrease they are able to retain/store water = minimal water loss

Characteristics Vascular structureswaxy coating prevents extra water from entering/exiting = better ability to retain water and beat the competition

heterotrophic diploid multicellulardevelop from blastula

Characteristics simplest multicellular animalasymmetricalno tissuesassexual (budding) + sexual reproduction (releasing sperm)

Characteristics 2 body forms - free swimming medusa, stationary polypgastrovascular cavity - mouth and anus are one openingradial symmetrynematocysts - within tentacles2 tissue layers - epidermis, gastrodermis

Characteristics bilateral symmetry - w/ head & tailcentralized nervous sys. - ladder like sys.3 layer tissuesAcoelomateNo circ. sys or hard skeleton

Characteristics bilateral symmetrycomplete digestive tractbody cavity - coelomatepseudocoelomate

Characteristics visceral massmantle - shellFoot / feetradula - structure near mouth used for scraping foodsshell or remnants of onecoelom

Lay soft eggsIncubate them like birdsHave mammary glands and make milkNo nipplesMilk is secreted onto the abdominal fur (platypus) or into a temporary pouch and licked off the skin (echidna)Long periods of maternal care1 offspring/year

mothers have to give birth earlierYoung are born extremely small relative to adult sizeHighly altricial youngthey live in the pouch to continue developing because they are so small and fragileBUT they are more advantageous to monotremes because it is harder to protect eggs from predators (compared to having them in a pouch), giving the marsupials a better chance at survival In the mother kangaroo's case, when conditions are unfavourable in her environment, she is able to pause their pregnancies

in comparison to marsupials, the placental mammals' offspring are:born nourished from the mother's uterus the placenta is attached and supplies nutrient via umbilical cordthey develop in their mother's body and are born when fully developed Making them less care intensive uterus The offspring are likely already able to walk and see after being born (in other words, they mature earlier than both monotremes and marsupials because of the better nutrition from the uterus)
