Exploring Multicellular Algae

What is a key characteristic that distinguishes multicellular algae from unicellular algae?

• Multicellular algae are always larger than unicellular algae.

• Multicellular algae have multiple cells, whereas unicellular algae consist of a single cell.

• Unicellular algae can photosynthesize, while multicellular algae cannot.

• Multicellular algae reproduce only asexually, unlike unicellular algae.

Name one example of green algae.

• Euglena

• Chlorella

• Dunaliella

• Spirulina

What type of cell organization can multicellular algae exhibit?

• Single-celled, branched, and clustered cell organization.

• Filamentous, thalloid, and colonial cell organization.

• Spherical, tubular, and layered cell organization.

• Cylindrical, flat, and dispersed cell organization.

Which multicellular algae is known as sea lettuce?

• Chlorella vulgaris

• Ulva lactuca

• Fucus vesiculosus

• Sargassum muticum

What is the largest species of algae?

• Sea lettuce (Ulva lactuca)

• Spirulina (Arthrospira platensis)

• Red algae (Rhodophyta)

• Giant kelp (Macrocystis pyrifera)

Identify a specialized function that some cells in multicellular algae may perform.

• Photosynthesis

• Waste excretion

• Nutrient absorption

• Cell division

Name one example of brown algae.

• Kelp

• Coral

• Seaweed

• Plankton

What is the significance of cell differentiation in multicellular algae?

• Cell differentiation leads to increased competition among cells.

• Cell differentiation enables specialization of functions, enhancing adaptability and efficiency in multicellular algae.

• Cell differentiation is irrelevant in unicellular organisms.

• Cell differentiation decreases the overall efficiency of algae.

Which multicellular algae is commonly used in sushi?

• kombu

• dulse

• nori

List one characteristic of thallus organization in multicellular algae.

• The body has specialized tissues for photosynthesis.

• The body is composed of distinct roots, stems, and leaves.

• The body is undifferentiated into true roots, stems, or leaves.

• The body is entirely unicellular in structure.
