With this very warm weather, many of us are opting not to walk our dogs until the late evening, when the sun’s strength is reduced. Its tempting to visit bodies of water for our dogs to cool off in too, but please steer well clear of stagnant ponds or any bodies of water that show a film, scum or algae. The water may be a breeding ground for a disease called Leptospirosis or may be playing host to blue-green algae. As the temperature of the water increases, so too does the likelihood of a highly toxic blue-gree algae bloom.

Internal transportation? Some of the larger kelps have translocation (transport of photosynthetic products) but most do not. They have no need for water-conducting tissues as they are, at leaset at some stage, surrounded by water. There are no seeds. Spores may be motile or non-motile, and this varies from phylum to phylum, e.g., the red and blue-green algae are non-flagellated and are essentially non-motile.

Algae are very simple chlorophyll-containing organisms: some say that they are plants; other say that the are not, calling them protists or protoctists. According to the most recent phylogenetic studies, both are not quite correct. Some algae (most the greens and the reds) are indeed related to the land plants, and some flagellated algae are related to the protists, but there is no justification for the including all algae in any generic term other than "algae".

...are increasingly overgrown and replaced by a turf of coralline algae, and by many types of soft annual seaweeds as shown here. A membranous red seaweed here appears white in June, a signal of low fertility.

We use the term "algae" very loosely, simply because coralling them is so very difficult. As conceived in the broadest sense, algae are oxygen-generating, photosynthetic organisms other than embryophyte land plants, fungi and lichens. Quite simply, what we call "algae" is an artificial and highly heterogeneous aggregation of organisms belonging to many different evolutionary lineages, and therefore highly diverse from a genetic point of view. This genetic diversity is reflected in the enormous biodiversity exhibited by algae in terms of morphological, ultrastructural, ecological, biochemical, and physiological traits.

Marine macroalgae, or seaweeds, are plant-like organisms that generally live
attached to rock or other hard substrata in coastal areas. They belong to three
different groups, empirically distinguished since the mid-nineteenth century by the Irish botanist William Henry Harvey (1811-1866) on the basis of thallus color: red algae (phylum Rhodophyta), brown algae (phylum Ochrophyta, class Phaeophyceae), and green algae (phylum Chlorophyta, classes Bryopsidophyceae, Chlorophyceae, Dasycladophyceae, Prasinophyceae, and Ulvophyceae). Distinguishing these three groups, however, involves more substantial differences than indicated by this simple designation. In addition to the pigmentation, they differ considerably in many ultrastructural and biochemical features including photosynthetic pigments, storage compounds, composition of cell walls, presence/absence of flagella, ultrastructure of mitosis, connections between adjacent cells, and the fine structure of the chloroplasts. In general, we can say that they are simple organisms composed of one cell, or grouped together in colonies, or as organisms with many cells, sometimes collaborating together as simple tissues.

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .

some experiments on photosynthesis in marine algae ..

Besides noting a further decline in Irish moss in 2005, I have seen a continuing decline in kelp (at the sheltered extremes of its range) and, similarly, in subtidal rockweeds. The novel view of just below the surface in sheltered inlets is becoming ever wider. Again, the loss of subtidal kelp and rockweed in these areas cannot be explained by ice scour (the explanation that I also initially assumed for this pattern of seaweed disappearance). Decaying older rockweeds, and kelp stumps, are seen on now-visible white granite boulders in shallow water, that were historically obscured by a canopy of dark seaweed. A contraction of the depth range of rockweeds has been reported in other parts of the world in recent years (e.g. the Baltic Sea). In these other areas the loss of subtidal rockweeds has been attributed to decreased light availability resulting from a pollution-induced increase in phytoplankton biomass. However, this does not seem to be a plausible explanation for the loss of rockweeds observed here. Rockweeds have a fairly high tolerance to air exposure, and photosynthesis in these plants actually occurs most efficiently in this situation (partial drying). Therefore, rockweeds growing in the intertidal zone might be expected to survive for the longest time under a scenario of declining nutrient availability, and the recently observed range contraction of these seaweeds might be predictable if ocean fertility should fall.

Why the rate of Photosynthesis is higher in red light …

Irish moss inside a sheltered nook at the low tide mark survived whatever stressor removed it from more exposed rocks. If ice had removed the moss, the same effect should have been felt by the rockweed.

Algae of other groups usually have two flagella (singular: flagellum). Reproduction may be isogamous, anisogamous, or oogamous. Female gametangia are not enclosed by a wall of sterile cells as in higher cryptogams. Mostly autotrophic (photosynthetic), pigments very variable and are the basis of classification; all have chlorophyll a; some have b, others c; all have accessory pigments of some kind e.g. phycocyanin (blueish), phycoerythrin (reddish), carotenes (yellow-brown), xanthophylls (brown, notably fucoxanthin found in brown algae).

Careful monitoring and management are the keys to most successful ponds, however there are ways to make life easier. A well designed pond can reduce the algae problems, by not creating an environment where the algae can flourish.
