Multiple choice biology plant kingdom classification of bryophytes types of bryophytes bryophyta

The female sex organ in Riccia and Funaria is _____________.

  1. antheridium

  2. paraphysis

  3. archegonium

  4. oogonium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The sex organs in bryophytes (Riccia, Funaria), are multicellular and jacketed. The jacket of the sterile cell around the sperm and egg is an adaptation to a life on land. The male reproductive organs are antheridia and female reproductive organs are archegonia.

So the correct option is B.

  3. Phylogenetic relationships

  4. All
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

R.H. Whittaker's five-kingdom classification system utilized cell structure, body organization, mode of nutrition, reproduction, and phylogenetic relationships as the primary criteria.

Multiple choice

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the Linnaean classification system, the hierarchy goes from Domain, Kingdom, Phylum, Class, Order, Family, Genus, to Species. Therefore, Genus is a higher, more inclusive rank than Species.

Multiple choice

Group of similar orders.

  1. Class

  2. Domain

  3. Biodiversity

  4. Food Web

  1. Greek

  2. medium

  3. Scientific name

  4. classifcation

  1. botany

  2. olericulture

  3. hort

  4. none

A Correct answer
Explanation

Botany is the scientific study of plants, encompassing their structure (anatomy), function (physiology), classification (taxonomy), and relationships with the environment. Note: 'physlolgy' is a typo for physiology.

Multiple choice

Ferns, club mosses, and horsetails are examples of _____________________________

  1. seed vascular plants

  2. non vacular plants

  3. flowering plants

  4. seedles vascular plants

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ferns, club mosses, and horsetails are seedless vascular plants. They have vascular tissue for transport (unlike mosses) but reproduce using spores rather than seeds (unlike conifers and flowering plants). They were dominant plants in the Carboniferous period.

Multiple choice

Why are liverworts small plants? 

  1. Because they reproduce asexually

  2. Because they do not have chloroplast

  3. Because the cannot photosynthesized

  4. Because they do not have a vascular system
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Liverworts are nonvascular plants; the lack of a vascular system limits their ability to transport water and nutrients, restricting their size.

Multiple choice

Hornworts do not have ________________

  1. chloroplasts

  2. chlorophyll

  3. xylem

  4. leaves

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hornworts are non-vascular plants, meaning they lack specialized tissues like xylem and phloem for transporting water and nutrients. They do possess chloroplasts and chlorophyll for photosynthesis.
