How are plantae protists similar and different from plant cells?

The Attempt at a Solution

similarity: both are photosynthetic, and producers, both are paraphylitic

differences: protists are unicellular whereas plants are multicellular, plants are big and complex where as protists are microscopic, more diverse and abundant. some protists could move, plants can't move. there are differences in chlorophyll and cell wall composition, also some protists don't have cell wall. I assume that there are reproductive differences (not very certain what it might be, I only know that they have a life cycle called alteration of generation that maybe slightly different from plants). some protists could be heterotrophic where plants can't be.

* any feedback is appreciated, thanks*

The classification and taxonomy of protists is actually rather complicated and is changing all the time so my textbooks will not be as up to date as the links below.

Wiki states the actual term protist is obsolete

A comparison list below, I would cross reference this with an up to date micro book. (They use the term protist)

The differences between plant cells and plantae protists are:
1. Complexity
Plant cells' nuclear DNA strands are more complicated than protists'. This is because plant cells have the ability to develop into distinct types based on their structure and function thanks to the presence of genes. Plants have the potential to grow into more sophisticated organisms than protists because totipotency promotes the creation of specialized tissues.

In actuality, all plants are multicellular, unlike protozoa. While some protists are unicellular, others reside in colonies of separate cells that interact and work together on activities like feeding and mobility. The protist group only has these colonies. Other protists, like seaweed, are multicellular and can even grow to be quite huge.

2. Nutrition
The main producers are plants, which are autotrophs that make food from inorganic molecules. There aren't any plants that are parasites that depend on other plants for nourishment. Some protists, like algae, are autotrophs that use chloroplasts to perform the photosynthetic process similarly to other protists. Other protists, referred to as heterotrophs or consumers, on the other hand, acquire nutrition in the form of organic molecules.

Several predatory and parasitic species of protists, collectively referred to as "protozoans," prey on bacteria and other protists. Protists have been linked to illnesses in both people and animals. Other protists, such slime molds, which resemble fungi and function as decomposers, are also protists.

3. Respiration
For the process of cellular respiration, oxygen is needed by plants. Protists differ here. While certain protist species are facultative anaerobes, which can break down carbohydrates without the presence of oxygen, some protist species are also aerobes. Even mud and mammalian digestive tracts include obligatory anaerobic protist species. There may be facultative aerobic adaptations in some plant tissues.

4. Movement
Many protists have specific cellular architectures that serve as sensory organs as well as aid in locomotion and eating. Flagella are tail-like organelles that help creatures move in a manner akin to swimming. Cilia are shorter, hair-like structures that are often abundant on the cell membrane's outside. Pseudopodia are cellular extensions that play a sensory role in locating and ingesting food as well as in protist movement.

On the other hand, plants are sedentary forms of life. Tropisms, or movements that only affect a single plant individual's organs, are permitted. While thigmotropism is movement in reaction to a physical stimulation, such the twining of tendrils, phototropism is the movement of plant parts toward sunshine.
