Algae
Plants in the ocean are mostly microscopic in size because being small allows them to maximize their surface area for nutrient absorption and light capture. This is important in the ocean where resources are limited. Additionally, being small helps these plants to better withstand ocean currents and turbulence.
Plankton
Plankton, Zooplankton, Planaria, Algae (Algae are plants, growing in the water.) {Wrong category: This isn't a Gorillas category question: this is a Marine Animals or Marine Plants question, or an Ocean or Water question.}
Microscopic plants growing in decaying matter are called saprophytic plants, which obtain their nutrients from dead organic matter through decomposition. Examples include fungi like molds and yeast.
whale
They are microscopic marine plants that are the beginning of the food chain in the ocean.
Answer is The epipelagic zone
Plankton are microscopic sea creatures, and the term includes both animals and plants.
Some are called single celled organisms. But I am not sure if all of them are called that though.
Microscopic plants rely on the suns rays for food just like other plants. This is because microscopic plants need to photosynthesize too.
Some examples of ocean plants include seaweed (such as kelp and algae), seagrasses (like eelgrass and turtle grass), and phytoplankton (microscopic plant-like organisms). These ocean plants play important roles in the marine ecosystem by providing food and habitat for various marine organisms.
Plankton are microscopic organisms that live in the ocean. Zooplankton are tiny animals. Phytoplankton are tiny plants. Some examples of phytoplankton include many types of algae, or single-celled plants.
