MTTC 103 In-Depth Study Test | Integrated science
Elementary Education Exam Questions with Verified
Solutions 2025/2026
Seed coat - correct answer protective covering on seed
Cotyldeon - correct answer small seed leaf; emerges when seed germinates
Endosperm - correct answer food supply in the seed
Apical meristem - correct answer area of cell division
Pedicel - correct answer supports weight of the flower
Divergent Evolution (or speciation) - correct answer Divergence of a new
species from a previous form of that species. Can happen by allopatric speciation
(geographical isolation) or adaptive radiation (creation of several new species
from a single parent species).
Convergent Evolution - correct answer difference species develop similar traits
from inhabiting similar environments; only superficial, the different species can't
interbreed
Causes of Evolution - correct answer Increase variation: mutations, sexual
reproduction, immigration, large population, and variation in geographic local.
Decrease variation: natural selection, emigration, small population, and random
mating
Population - correct answer Group of the same species in a specific area
Community - correct answer Group of populations residing in the same area
,Biomes - correct answer Communities that are ecologically similar in regards to
temperature, rainfall and the species that live there
Succession - correct answer replacing a community that has been damaged or
has begun where no life previously existed
Carrying Capacity - correct answer Amount of life a habitat can support
Basic Requirements for Life - correct answer Food and Water, Sunlight and Air,
Shelter and Space
Biotic and Abiotic factors - correct answer Biotic - living
Abiotic - non-living
Carbon Cycle - correct answer Plants fix carbon in the form of glucose and then
animals obtain carbon by eating plants
Nitrogen Cycle - correct answer Bacteria are able to breakdown nitrogen, so
then it is in the soil, which goes into plants, and is able to be obtained by animals
Phosphorus Cycle - correct answer Exists as a mineral, taken up by plants, then
eaten by animals. Urine and decayed matter return it to soil.
Atomic theory - correct answer Atoms are the basic, smallest building units of
matter
Dmitri Mendeleev - correct answer Invented the Periodic Table of Elements
,Law of Chemical Periodicity - properties of the various elements are functions of
atomic number
Receptacle - correct answer holds floral organs at flowers base
Sepals - correct answer Cover the flower prior to blooming
Petals - correct answer Attract insects to assist in pollination
Anther - correct answer Male part that produces pollen
Filament - correct answer Supports the anther
Style - correct answer Tube that leads to the ovary (female)
Stigma - correct answer Female part that holds pollen that came from the male
part
Ovary - correct answer contains the ovules
Photosynthesis - correct answer Plants make carbohydrates from the energy of
the sun, carbon dioxide, and water. Oxygen in a waste product. Occurs in the
chloroplast
Light reactions - correct answer reactions of photosynthesis that use energy
from light to produce ATP and NADPH
Dark reactions - correct answer Reactions of photosynthesis that do not require
light but use energy produced and stored during light reactions to make glucose
, Respiration - correct answer Glucose, with the help of oxygen, breaks down and
produces carbon dioxide and water as waste.
Transpiration - correct answer Water travels up xylem of the plant. Head and
wind increase transpiration, high humidity decreases it
Angiosperms - correct answer A flowering plant, which forms seeds inside a
protective chamber called an ovary.
Double fertilization - correct answer a fertilization process that requires two
sperm to fuse with two other cells
Seed dispersal - correct answer scattering of seeds; can be done by animals,
insects, air, or water
Organization of Life - correct answer Atoms > molecules > organelles > cells >
tissues > organs > organ systems > organism
Skeletal system - correct answer function is support
Muscular system - correct answer function is for movement; 3 types: skeletal
(attached to bones), smooth (in organs), cardiac (specialized smooth muscle)
Nervous System - correct answer Basic unit is a neuron - consists of an axon
(carries impulses away from cell body), dendrite (carries impulses towards body),
and cell body (contains nucleus)
Synapses - correct answer spaces between neurons
