characteristics and classification of living organisms Flashcards

Question

fungus kingdom

Answer 1

an organism whose cells have cell walls, but does not photosynthesise eg. mushrooms main body is made up of hypae dont have chlorophyll and dont photosynthesise they feed saprophytically or parasitically by feeding on organic materials such as faeces are decomposers reproduce by forming spores usually mulit-cellular but some are uni-cellular cell walls made of chitin

Answer 2

organisms that break down orgainc substances outside their bodies, releasing nutrients from them that other organisms can use

Answer 3

very small groups of cells surrounding by a protective wall, used in reproduction

Answer 4

mixed collection or organisms all have cells w nucleus most are unicellular but some are multi some feed by photosynthesis others by feeding on organic substances made by other organisms

Answer 5

huge number of organisms bacteria dont have a nucleus some can do photosynthesis usually unicellular cells walls made of peptidoglycan no mitochondria circular loop of DNA which is free in the cytoplasm often have plasmids, loops of DNA found in the cytoplasm

Answer 6

animals that have backbones - fish - amphibians - reptiles - birds - mammals

Answer 7

vertebrates with scaly skin gills throughout their life have fins eggs have no shell, are laid in water

Answer 8

undergo metamorphosis vertebrates with skin eggs have no shells and laid underwater tadpoles live in water, adults often live on land tadpoles have gills, adults have lungs for gas exchange

Answer 9

changing from a larva with one body form to a adult with a different body form

Answer 10

vertebrate with scaly skin lay eggs with soft shells

Answer 11

feathers sometimes scales have a beak front 2 limbs are wings, not all can fly lay eggs with hard shells

Answer 12

have a pinna (earflap) have a uterus and placenta have mammary glands hair on their skin young develop in uterus produce milk to young different teeth sweat glands have a diaphragm

Answer 13

organs found only in mammals, which produce milk to feed young

Answer 14

a muscles that separates the chest cavity from the abdominal cavity in mammals; it helps with breathing

Answer 15

animals with jointed legs but no backbone waterproof exoskeleton several pairs of jointed legs diff groups of arthropods: insects, crustaceans, arachnids. myriapods

Answer 16

arthropods w 3 pairs of jointed legs 2 pairs of wings, one or both may be vestigial breath through tubes called tracheae body divided in head, thorax and abdomen one pair of antennae

Answer 17

living on land

Answer 18

description of a structure that has evolved to become so small that it is no longer useful

Answer 19

aquatic breath through gills arthropods with more that 4 pairs of jointed legs 2 pairs of antennae crabs

Answer 20

spiders arthropods with 4 pairs of jointed legs no antennae body is divided into 2 parts: cephalothorax and abdomen

Answer 21

centipedes or millipedes body consists of similar segments each segments has jointed legs one pair of antennae

Answer 22

plants with leaves called fronds no production of flowers reproduce by spores underside of fronds plants with roots, stems, and leaves

Answer 23

plants with roots stems and leaves reproduce using flowers and seeds seeds are produced inside ovary in the flower divided into 2 groups: dicotyledons, monocotyledons

Answer 24

have seeds with 2 cotyledons one main root with side roots coming out of it leaves in network of veins petals in multiples of 4 or 5 vascular bundles in the stem, arranged in a ring

Answer 25

seed with 1 cotyledon roots grow out directly from the stem leaves have parallel veins petals in multiples of 3 vascular bundles in the stem arranged randomly

Answer 26

not considered living organism bc cant do anything until living inside a cell take over cells machinery to make multiple copies of themselves new viruse burst out of the cell and invade others host cells is usually killed when this happens
